Short Description:<\/strong> Complete guide to South Korea\u2019s D-2-5 Student Visa for research study: eligibility, documents, work rights, dependents, extensions, costs, and official rules.<\/p>\n\n\n\n Last Verified On:<\/strong> April 7, 2026<\/p>\n\n\n\n The D-2-5<\/strong> is a South Korean student residence status<\/strong> used for research study<\/strong>. It is part of the broader D-2 Student<\/strong> visa family.<\/p>\n\n\n\n In practical terms, it is used by a foreign national who has been admitted to a research-focused academic program<\/strong> in South Korea, rather than a standard language course or ordinary full degree class stream. It commonly applies to students undertaking research courses, thesis work, or academic research affiliation<\/strong> under a university or similar recognized institution.<\/p>\n\n\n\n In South Korea\u2019s immigration system, this is generally a long-stay visa\/status route<\/strong> that begins with:\n– a visa issued overseas by a Korean embassy\/consulate, or\n– in some cases, a change of status in Korea if legally permitted.<\/p>\n\n\n\n After arrival, the holder usually needs to complete foreigner registration<\/strong> and maintain a lawful sojourn status<\/strong>.<\/p>\n\n\n\n South Korea groups visa\/status categories by purpose. For study-related cases, the main categories commonly include:\n– D-2<\/strong>: Student\n– D-4<\/strong>: General training \/ language training and some non-degree training<\/p>\n\n\n\n Within D-2, there are multiple subtypes. D-2-5<\/strong> is the subtype tied to research study<\/strong>.<\/p>\n\n\n\n This category is commonly referred to as:\n– D-2-5<\/strong>\n– Student (Research Study)<\/strong>\n– Research Course \/ Research Student<\/strong> under D-2<\/p>\n\n\n\n Korean-language administrative naming may vary slightly by ministry, embassy, and university materials. The controlling point is the D-2-5 code<\/strong>, not how a local office translates the label into English.<\/p>\n\n\n\n Warning:<\/strong> South Korean immigration uses both \u201cvisa\u201d language and \u201cstatus of stay\/sojourn status\u201d language. The visa in your passport gets you to the border; your legal stay inside Korea is governed by the status and period of stay granted under immigration rules.<\/p>\n<\/blockquote>\n\n\n\n The D-2-5 is usually right for:\n– Research students<\/strong> accepted by a Korean university or similar academic institution\n– Graduate-level researchers<\/strong> doing thesis or supervised research\n– Exchange or visiting research students<\/strong> where the Korean institution specifically classifies the stay as research study under D-2-5\n– Students moving from coursework into research-only stage<\/strong>, if the school and immigration classify it that way<\/p>\n\n\n\n You should not<\/strong> use D-2-5 if your real purpose is:\n– language study only\n– tourism\n– paid employment\n– business setup\n– internship unrelated to an approved academic program\n– full-time research employment\n– family reunion only<\/p>\n\n\n\n The D-2-5 is used for:\n– formal research study<\/strong>\n– academic thesis research<\/strong>\n– supervised university-based research enrollment<\/strong>\n– participation in a qualifying research program at an approved Korean institution\n– residence in Korea for the duration of that approved research study\n– limited activities normally incidental to student life, where not separately prohibited<\/p>\n\n\n\n These areas are sensitive:\n– part-time work<\/strong>: often possible only with prior permission and subject to student work rules\n– internships<\/strong>: may require school approval and immigration authorization depending on structure\n– conference attendance<\/strong>: usually fine if tied to study\n– academic fieldwork<\/strong>: generally allowed if part of approved program and institutionally documented<\/p>\n\n\n\n The D-2-5 is generally not for<\/strong>:\n– tourism as the main purpose\n– full-time employment\n– unrestricted freelance work\n– ordinary remote work for a foreign employer without checking Korean immigration\/tax implications\n– business incorporation for active commercial operations\n– journalism\n– missionary\/religious work\n– paid performance unrelated to student status\n– undeclared internships\n– medical treatment as the primary reason for stay\n– transit-only travel<\/p>\n\n\n\n South Korean immigration materials do not always spell out every remote-work scenario for student status. If you plan to:\n– work online for a foreign company,\n– freelance remotely,\n– receive payments while in Korea,<\/p>\n\n\n\n you should verify with Korea Immigration Service<\/strong> whether this is allowed under your status or requires separate authorization. Do not<\/strong> assume \u201cwork outside Korea\u201d is automatically allowed.<\/p>\n\n\n\n Unpaid volunteering may still be treated as an activity outside status if it resembles work or organized service. Check first if the role is structured, recurring, or institution-based.<\/p>\n\n\n\n If you are employed<\/strong> by a research institute, you may need a work status instead. If you are enrolled as a student researcher<\/strong>, D-2-5 may be correct.<\/p>\n\n\n\n Officially, this sits within the D-2 Student<\/strong> category.<\/p>\n\n\n\n Common English label:\n– Student Visa – Research Study<\/strong>\n– Student (Research Study)<\/strong><\/p>\n\n\n\n The D-2 family includes several subcategories for:\n– associate degree\n– bachelor\u2019s\n– master\u2019s\n– doctorate\n– research study\n– exchange student\n– work-study linked streams in some classifications<\/p>\n\n\n\n The exact wording can vary slightly across official publications and embassy pages, but D-2-5 = research study<\/strong>.<\/p>\n\n\n\n Official requirements can vary by:\n– embassy\/consulate\n– nationality\n– school type\n– whether you apply overseas or change status in Korea\n– whether you are scholarship-funded or privately funded<\/p>\n\n\n\n To qualify for D-2-5, an applicant generally must:\n– have a valid passport\n– be admitted\/accepted to a qualifying research study program<\/strong> at a recognized Korean institution\n– provide the institution\u2019s official documents\n– show ability to support living and study costs\n– meet immigration admissibility requirements\n– intend to stay for the stated academic purpose\n– comply with Korean registration and status rules after arrival<\/p>\n\n\n\n There is no general public rule saying only certain nationalities can use D-2-5. However:\n– document requirements,\n– visa issuance procedures,\n– interview frequency,\n– apostille\/legalization expectations,<\/p>\n\n\n\n may differ by nationality and place of application.<\/p>\n\n\n\n Your passport should be valid long enough for visa issuance, travel, and registration. Some embassies prefer substantial remaining validity. If your passport is near expiry, renew before applying if possible.<\/p>\n\n\n\n There is no widely published single age rule unique to D-2-5. The deciding factor is usually lawful admission to the research program and ability to qualify as a student researcher.<\/p>\n\n\n\n You must normally show educational background appropriate for admission to the research course.<\/p>\n\n\n\n No universal immigration-language threshold is publicly stated specifically for D-2-5. However:\n– the school may require Korean or English proficiency,\n– the embassy may review whether your academic plan is credible.<\/p>\n\n\n\n A sponsoring academic institution is usually central. You normally need:\n– admission\/acceptance,\n– certificate of business registration for the school or equivalent,\n– sometimes tuition\/payment or scholarship confirmation.<\/p>\n\n\n\n Not required.<\/p>\n\n\n\n Not applicable for this visa.<\/p>\n\n\n\n Only relevant for dependents.<\/p>\n\n\n\n Yes, this is one of the most important documents.<\/p>\n\n\n\n Yes. You usually need to show you can pay:\n– tuition or research-related costs where applicable\n– living expenses\n– housing\/start-up costs<\/p>\n\n\n\n Exact financial thresholds can vary by institution and embassy.<\/p>\n\n\n\n May be requested, especially by some posts.<\/p>\n\n\n\n Not always required at visa stage, but proof of travel plan can sometimes help.<\/p>\n\n\n\n Some applicants may need a health check depending on country, institution, or later registration requirements.<\/p>\n\n\n\n Not always required for every D-2-5 application, but can be requested in some contexts. Applicants with serious criminal or immigration issues may be refused.<\/p>\n\n\n\n Universities may require insurance, and students in Korea can become subject to national health insurance rules. Pre-arrival insurance requirements vary.<\/p>\n\n\n\n Whether biometrics are taken depends on the embassy\/consulate or local process.<\/p>\n\n\n\n You must show a genuine student\/research purpose.<\/p>\n\n\n\n Korean student visas are not usually described in \u201cdual intent\u201d language the way some countries do. You should present a truthful study purpose. Long-term future plans should not contradict your immediate lawful purpose.<\/p>\n\n\n\n Some embassies only accept applications from:\n– nationals of the country where the embassy is located, or\n– foreign residents legally residing there.<\/p>\n\n\n\n After arrival, long-term students usually must apply for foreigner registration<\/strong> within the legal deadline.<\/p>\n\n\n\n No public general lottery or quota system is typically published for D-2-5 itself.<\/p>\n\n\n\n These are very important. Some embassies may ask for:\n– apostilled academic records\n– local bank statements\n– tuberculosis test\n– criminal record check\n– visa application through a designated center<\/p>\n\n\n\n Warning:<\/strong> Always use the checklist of the exact Korean embassy\/consulate where you will apply. Document rules vary.<\/p>\n<\/blockquote>\n\n\n\n You may be ineligible or face refusal if:\n– you are not genuinely admitted to a qualifying research program\n– the institution is not recognized for the intended visa\n– your documents are false, altered, or unverifiable\n– your finances are weak or unclear\n– your intended activity is really work, not study\n– you have serious prior immigration violations\n– you pose a security, criminal, or public-order concern<\/p>\n\n\n\n The D-2-5 can be useful as a stepping-stone toward:\n– other study statuses\n– job-seeking after graduation\/research completion where allowed\n– work visas\n– long-term residence routes<\/p>\n\n\n\n Although this is a research category, institutions still generally report student status. Problems can arise if:\n– you stop participating,\n– your research status lapses,\n– you are dismissed or withdraw,\n– your school reports noncompliance.<\/p>\n\n\n\n You may need to report:\n– address changes\n– passport changes\n– school transfer or program changes\n– changes in personal details<\/p>\n\n\n\n A visa sticker alone does not guarantee unlimited re-entry. Your re-entry position may depend on:\n– current registration status\n– period of stay\n– whether your status remains valid\n– current immigration rules at the time of travel<\/p>\n\n\n\n The visa\u2019s validity period<\/strong> is the period during which you can use it to enter Korea. This is different from your period of stay<\/strong> after entry.<\/p>\n\n\n\n The actual stay is generally tied to:\n– your admission\/research period\n– immigration decision at issuance or after registration\/extension<\/p>\n\n\n\n This may vary by case and embassy issuance practice.<\/p>\n\n\n\n Check:\n– visa sticker details, if any\n– entry stamp\/digital entry record\n– foreigner registration status\n– later extension approval notice<\/p>\n\n\n\n Do not assume a grace period exists after visa\/status expiry. South Korea treats overstays seriously.<\/p>\n\n\n\n Possible consequences include:\n– fines\n– future visa refusal\n– restrictions on changes\/extensions\n– removal\/deportation in severe cases<\/p>\n\n\n\n Apply for extension before<\/strong> your period of stay expires. Do not wait until the last day if avoidable.<\/p>\n\n\n\n If you do not enter Korea within the visa validity period, the visa normally expires unused.<\/p>\n\n\n\n South Korea does not generally describe this using \u201cbridging visa\u201d terminology. If you file an in-time extension or change application, confirm directly with immigration whether you may remain lawfully while it is pending.<\/p>\n\n\n\n Document requirements vary by embassy and school. Below is the most complete practical checklist.<\/p>\n\n\n\n Usually not central for D-2-5, but may help show financial stability:\n– applicant\u2019s employment certificate\n– sponsor\u2019s employment certificate\n– sponsor\u2019s tax\/payment evidence where requested<\/p>\n\n\n\n If using family support or bringing dependents:\n– birth certificate\n– marriage certificate\n– family relation certificate\n– custody\/consent documents for minors<\/p>\n\n\n\n Depending on embassy\/nationality:\n– apostille\/legalization on academic records\n– criminal record certificate\n– tuberculosis screening\n– local residence proof\n– parental consent for younger applicants<\/p>\n\n\n\n For minors:\n– birth certificate\n– both parents\u2019 consent\n– passport copies of parents\n– legal guardian papers if applicable<\/p>\n\n\n\n For dependents:\n– relationship proof\n– financial support proof\n– principal applicant\u2019s visa\/status documents<\/p>\n\n\n\n This varies significantly. Documents may need to be:\n– translated into Korean or English\n– notarized\n– apostilled\n– consular legalized<\/p>\n\n\n\n Use the embassy\u2019s exact instructions.<\/p>\n\n\n\n Common Mistake:<\/strong> Applicants often assume English-only documents are always accepted. Some posts require notarized translations even if the document appears understandable.<\/p>\n<\/blockquote>\n\n\n\n Use the exact photo specifications published by the embassy or visa portal. Common issues:\n– old photo\n– incorrect background\n– glasses glare\n– wrong dimensions<\/p>\n\n\n\n A single universal D-2-5 financial threshold is not always published consistently across all official pages. In practice, required funds may depend on:\n– school location\n– tuition amount\n– program length\n– scholarship coverage\n– embassy-specific checklist<\/p>\n\n\n\n Usually:\n– parents\n– legal guardians\n– sometimes spouse\n– scholarship body\n– university or professor-funded program, if formally documented<\/p>\n\n\n\n Some embassies care whether money was deposited recently. If there is a large recent deposit:\n– explain it,\n– document the source,\n– include sale deed, salary bonus record, scholarship transfer notice, or family transfer explanation if true.<\/p>\n\n\n\n Fees vary by nationality, reciprocity, embassy, and whether a visa application center is used.<\/p>\n\n\n\n Warning:<\/strong> Check the latest official fee page. Korean visa fees are often based on reciprocity and can differ by country and single\/multiple-entry type.<\/p>\n<\/blockquote>\n\n\n\n Make sure your school confirms that your program is classified as D-2-5 research study<\/strong>.<\/p>\n\n\n\n Obtain:\n– admission\/acceptance letter\n– certificate of admission if issued\n– business registration or school registration documents if required\n– scholarship\/funding letter if applicable<\/p>\n\n\n\n Prepare:\n– passport\n– photos\n– financial evidence\n– academic documents\n– translations\/apostilles if required<\/p>\n\n\n\n Use the official Korean visa application form or online system if available through your location.<\/p>\n\n\n\n Some posts require advance booking.<\/p>\n\n\n\n Pay as instructed by the embassy\/consulate or visa center.<\/p>\n\n\n\n Submission may be:\n– directly to embassy\/consulate\n– through an authorized visa application center\n– through a Korean sponsor-issued visa issuance confirmation process in some cases<\/p>\n\n\n\n Not all applicants are interviewed, but some are.<\/p>\n\n\n\n Tracking options depend on the post and portal.<\/p>\n\n\n\n If the embassy requests updated bank statements, school clarifications, or corrected forms, reply promptly.<\/p>\n\n\n\n If approved, you receive:\n– visa sticker, or\n– visa grant details \/ issuance confirmation depending on process<\/p>\n\n\n\n Carry key supporting documents in hand luggage.<\/p>\n\n\n\n Enter Korea and ensure your entry details are correct.<\/p>\n\n\n\n Long-term residents generally must apply for foreigner registration<\/strong> within the legal deadline.<\/p>\n\n\n\n Enroll, attend\/or participate in research, update address, and apply for extension on time.<\/p>\n\n\n\n There is no single universal published D-2-5 processing time valid for all embassies.<\/p>\n\n\n\n Applicants often should allow several weeks<\/strong>, and longer during major university intake periods.<\/p>\n\n\n\n Pro Tip:<\/strong> Apply as early as your school and embassy permit, especially before semester starts.<\/p>\n<\/blockquote>\n\n\n\n May be required depending on application location and local procedure.<\/p>\n\n\n\n Not every student is interviewed. If called, expect questions such as:\n– Why did you choose this university?\n– What is your research topic?\n– Who is funding your stay?\n– What is your academic background?\n– Where will you live?<\/p>\n\n\n\n A medical check is not universally published as mandatory for all D-2-5 applicants, but:\n– some embassies may request health-related documents,\n– universities may require health clearance,\n– later residence steps may involve health insurance or screening obligations.<\/p>\n\n\n\n Not universally required for every D-2-5 case, but some posts may ask for it.<\/p>\n\n\n\n If police or medical documents are required, they usually must be recent. Check the embassy\u2019s accepted validity window.<\/p>\n\n\n\n Official public approval-rate data specifically for D-2-5<\/strong> is not generally published in an accessible form.<\/p>\n\n\n\n Based on official practice and common visa logic, refusals often involve:\n– weak or inconsistent financial evidence\n– poor alignment between school documents and visa category\n– doubts about genuine student intent\n– missing legalization\/translation requirements\n– prior immigration violations\n– inability to verify sponsor or institution documents<\/p>\n\n\n\n Ask your school:\n– Is this definitely D-2-5<\/strong>?\n– Can you issue documents clearly stating research study status?<\/p>\n\n\n\n If funded by parents or sponsor, include:\n– sponsorship letter\n– relationship proof\n– bank statements\n– employment\/income evidence of sponsor if useful<\/p>\n\n\n\n Add a short note for:\n– recent deposits\n– foreign currency transfers\n– scholarship disbursements\n– account ownership issues<\/p>\n\n\n\n Your:\n– prior studies,\n– proposed research,\n– host institution,\n– long-term academic plan<\/p>\n\n\n\n should all align.<\/p>\n\n\n\n A one-page index helps the reviewing officer navigate your file.<\/p>\n\n\n\n Do not submit informal translations if certified\/notarized versions are required.<\/p>\n\n\n\n Give time for corrections and extra requests.<\/p>\n\n\n\n If you had a previous refusal for Korea or another country, disclose it if asked and explain what changed.<\/p>\n\n\n\n Pro Tip:<\/strong> Ask your university international office for the exact visa label they expect. Many applicant errors happen because the program is really D-2, but the wrong subtype is assumed.<\/p>\n<\/blockquote>\n\n\n\n Contact the embassy when:\n– your checklist is unclear,\n– your nationality has special rules,\n– your application is unusual.<\/p>\n\n\n\n Do not contact repeatedly just to ask whether ordinary processing has finished before the standard timeframe.<\/p>\n\n\n\n If dependents will follow later:\n– secure the principal student\u2019s status first if timing is tight,\n– keep relationship documents ready in apostilled\/translated form.<\/p>\n\n\n\n If refused:\n– identify the exact missing or weak point,\n– fix it with better evidence,\n– do not simply resubmit the same pack unchanged.<\/p>\n\n\n\n A cover letter is not always mandatory, but it is often helpful.<\/p>\n\n\n\n Include a concise letter if:\n– your funding is complex\n– your research path needs explanation\n– your academic history is non-linear\n– you are applying from a third country\n– you had prior refusals or immigration issues<\/p>\n\n\n\n Possible sponsors include:\n– parents\n– spouse\n– scholarship body\n– Korean university\n– research supervisor\/institution, where formally structured<\/p>\n\n\n\n The sponsor should be able to show:\n– financial ability\n– genuine relationship or formal institutional support\n– consistency with the applicant\u2019s story<\/p>\n\n\n\n A good sponsor or institution letter should state:\n– applicant\u2019s name and passport number\n– institution\/sponsor details\n– nature of support\n– dates of support\n– financial or academic scope of support\n– signature and official seal where applicable<\/p>\n\n\n\n Potentially yes, usually through a dependent status such as F-3<\/strong>, subject to eligibility and immigration approval.<\/p>\n\n\n\n Typically:\n– legally married spouse\n– minor unmarried children<\/p>\n\n\n\n Unmarried partners are generally much harder and may not qualify unless a separate rule applies. Same-sex spouse\/partner recognition can be legally and administratively complex in Korea and may not be treated the same as opposite-sex married spouses for immigration purposes in all cases.<\/p>\n\n\n\n Dependents usually do not<\/strong> get open work rights automatically. Separate permission or another status may be needed. Children may study subject to local rules.<\/p>\n\n\n\n Yes. This is the core purpose of D-2-5.<\/p>\n\n\n\n Work is generally limited<\/strong>, not automatic.<\/p>\n\n\n\n Foreign students in Korea may be allowed part-time employment<\/strong> if they meet conditions and obtain required permission. Rules can depend on:\n– level of study\n– academic performance\/attendance\n– language ability\n– hours and job type\n– approval from school and immigration<\/p>\n\n\n\n Generally not freely allowed under a student status unless specifically authorized.<\/p>\n\n\n\n This is a grey area and should be checked directly with immigration. Do not assume unrestricted remote work is permitted.<\/p>\n\n\n\n Possible if academically related and properly authorized.<\/p>\n\n\n\n Only if genuinely volunteer-based and not a disguised employment activity.<\/p>\n\n\n\n Passive income such as savings interest is different from working income, but tax questions may still arise.<\/p>\n\n\n\n Incidental academic\/professional meetings are usually fine. Active business operations are not the purpose of D-2-5.<\/p>\n\n\n\n Even with an issued visa, final admission is decided at the border.<\/p>\n\n\n\n Bring:\n– passport\n– visa or issuance confirmation\n– admission\/acceptance letter\n– proof of housing\n– financial proof copies\n– school contact details<\/p>\n\n\n\n An officer may ask:\n– which university?\n– what are you studying\/researching?\n– how long will you stay?\n– where will you live?<\/p>\n\n\n\n A one-way ticket is common for long-stay students, but airlines may still ask for proof of visa\/status. Check airline requirements.<\/p>\n\n\n\n If you leave Korea during your studies, verify:\n– your status remains valid,\n– your registration is active,\n– any re-entry conditions are met at that time.<\/p>\n\n\n\n If your passport expires, carry both old and new passports if your visa evidence is linked to the old passport, and update immigration records as needed.<\/p>\n\n\n\n Yes, usually if:\n– your research continues,\n– your school confirms ongoing enrollment\/status,\n– you still meet financial and compliance requirements.<\/p>\n\n\n\n Extensions are generally handled inside Korea<\/strong> through immigration\/HiKorea processes.<\/p>\n\n\n\n Possible in some cases, depending on eligibility, such as:\n– another D-2 subtype\n– D-10 after completion if eligible\n– E-series work status if you obtain qualifying employment\n– family-based status where lawful and supported<\/p>\n\n\n\n This can trigger reporting or prior approval requirements. Do not change institutions casually without checking immigration consequences.<\/p>\n\n\n\n If you fall out of status, options are limited and fact-specific. Overstay or lapse can be serious.<\/p>\n\n\n\n No, not directly.<\/p>\n\n\n\n Yes. It can help by:\n– giving lawful residence history,\n– allowing graduation or research completion in Korea,\n– supporting later transition to job-seeking or work status,\n– potentially contributing to longer-term immigration planning.<\/p>\n\n\n\n Whether time on D-2 counts fully for permanent residence or naturalization purposes can depend on:\n– the PR or citizenship route used later,\n– continuous lawful residence rules,\n– status transitions,\n– immigration policy in force at the time.<\/p>\n\n\n\n Naturalization in Korea usually requires broader residence, conduct, financial, and integration requirements. D-2-5 alone is not a citizenship route.<\/p>\n\n\n\n Long-term foreign residents generally must complete foreigner registration<\/strong> within the required deadline after arrival.<\/p>\n\n\n\n You must report changes of address as required by law.<\/p>\n\n\n\n If you work lawfully in Korea or stay long enough to trigger tax residence issues, Korean tax rules may apply. Student status does not automatically exempt you from tax obligations.<\/p>\n\n\n\n Foreign students may become subject to National Health Insurance Service<\/strong> rules depending on residence duration and current law.<\/p>\n\n\n\n You must maintain valid student\/research status with your institution.<\/p>\n\n\n\n Unauthorized work, false reporting, or overstay can lead to:\n– fines\n– visa cancellation\n– refusal of extension\n– removal<\/p>\n\n\n\n Even if your nationality has short-stay visa-free access to Korea, that does not<\/strong> replace the need for a proper long-stay student visa\/status for D-2-5 study.<\/p>\n\n\n\n Nationality can affect:\n– processing time\n– financial evidence level\n– legalization requirements\n– interview likelihood<\/p>\n\n\n\n Some embassies accept only:\n– nationals, or\n– foreigners legally resident in that country.<\/p>\n\n\n\n Check the embassy website before assuming you can apply there.<\/p>\n\n\n\n Possible but uncommon for a research-study route. Extra parental documents are likely required.<\/p>\n\n\n\n Provide custody orders, consent letters, or other legal documents for minors.<\/p>\n\n\n\n Use formal adoption\/custody documents if dependent applications are involved.<\/p>\n\n\n\n This area is sensitive. Korean immigration treatment may be limited or case-specific. Verify directly with the embassy or immigration before relying on dependent eligibility.<\/p>\n\n\n\n Possible additional documentation and identity verification issues may arise. These cases are highly individualized.<\/p>\n\n\n\n Use the passport you will travel with consistently. If holding Korean nationality as well, separate nationality law issues may arise.<\/p>\n\n\n\n Disclose when required and explain what changed.<\/p>\n\n\n\n Expect heightened scrutiny and possible refusal.<\/p>\n\n\n\n Renew the passport and carry both if travel is still possible; also check whether reissuance or record update is needed.<\/p>\n\n\n\n Provide legal proof of name change and, if relevant, an explanatory note matching all records.<\/p>\n\n\n\nVisa Snapshot<\/h2>\n\n\n\n
