The specific code <strong>D-3-12<\/strong> is commonly referred to as the <strong>Industrial Trainee (Technology) Visa<\/strong>.<\/p>\n\n\n\n<p>In plain English, this is a <strong>long-stay visa\/status for foreigners coming to Korea for approved technology or industrial training<\/strong>, rather than for ordinary tourism, degree study, or regular employment.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why it exists<\/h2>\n\n\n\n<p>This route exists to allow Korean entities to bring foreign nationals to Korea for <strong>structured, approved training activities<\/strong> connected to industrial or technical fields.<\/p>\n\n\n\n<p>It is <strong>not the same as a normal work visa<\/strong>. The central legal idea is that the person\u2019s main purpose in Korea is <strong>training<\/strong>, not open-market employment.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Who it is meant for<\/h2>\n\n\n\n<p>It is generally meant for people who:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>have a Korean host organization or company arranging the training<\/li>\n<li>will participate in a specific industrial or technical training program<\/li>\n<li>fit within Korea\u2019s immigration rules for trainee status<\/li>\n<li>are not entering primarily as employees under ordinary work-authorized statuses like E-series visas<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">How it fits into South Korea\u2019s immigration system<\/h2>\n\n\n\n<p>South Korea\u2019s visa system usually works as a combination of:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>a <strong>visa<\/strong> issued abroad by an embassy\/consulate, and<\/li>\n<li>a <strong>status of stay<\/strong> recognized by Korean immigration on entry and during residence<\/li>\n<\/ul>\n\n\n\n<p>For D-3-12, the foreign national usually needs:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>visa issuance or visa issuance confirmation procedures, and<\/li>\n<li>compliance with Korean immigration rules after arrival, including registration if required by length of stay<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">What kind of immigration route is this?<\/h2>\n\n\n\n<p>This is best understood as a:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>sticker visa or consular visa issuance route<\/strong> for entry, tied to<\/li>\n<li>a <strong>residence\/status-of-stay category<\/strong> under Korean immigration law<\/li>\n<\/ul>\n\n\n\n<p>It is <strong>not<\/strong> a visa-free waiver category, tourist permission, or general e-visa category in the ordinary sense.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Alternate names and labels<\/h2>\n\n\n\n<p>Possible names used in official or administrative contexts include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>D-3<\/strong><\/li>\n<li><strong>Industrial Training<\/strong><\/li>\n<li><strong>Industrial Trainee<\/strong><\/li>\n<li><strong>D-3-12 Industrial Trainee (Technology)<\/strong><\/li>\n<\/ul>\n\n\n\n<p>Korean-language naming and exact sublabels can appear differently across portals or mission pages. Korean official systems sometimes group D-3 at a higher category level and list subcodes separately. Where a consulate does not publish a D-3-12-specific page, applicants should confirm with the Korean mission handling their case.<\/p>\n\n\n\n<blockquote>\n<p><strong>Warning:<\/strong> South Korean visa pages are not always fully harmonized across all embassies and consulates. Some missions publish detailed subcategory checklists; others publish only the umbrella D-3 category or require applicants to use the Visa Navigator system.<\/p>\n<\/blockquote>\n\n\n\n<h1 class=\"wp-block-heading\">2. Who should apply for this visa?<\/h1>\n\n\n\n<h2 class=\"wp-block-heading\">Ideal applicants<\/h2>\n\n\n\n<p>This visa is most suitable for:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>foreign nationals invited for <strong>industrial or technical training<\/strong><\/li>\n<li>trainees under a <strong>company-to-company<\/strong> or institutional training arrangement<\/li>\n<li>people whose activity in Korea is clearly <strong>training-focused<\/strong>, not ordinary labor<\/li>\n<li>applicants with a Korean host that can document the purpose, schedule, and legal basis of training<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Who should generally not use this visa<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Tourists<\/h3>\n\n\n\n<p>Not appropriate. Use a:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>visa waiver, if eligible<\/li>\n<li><strong>C-3 short-term visit<\/strong> visa if required<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Business visitors<\/h3>\n\n\n\n<p>If the purpose is short business meetings, market research, contract discussions, or conferences, this is usually the wrong route. Consider:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>C-3-4 Business Visitor (where applicable)<\/strong><\/li>\n<li>another short-term business category<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Job seekers<\/h3>\n\n\n\n<p>This is not a general job-seeking route. Consider an appropriate Korean route such as:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>a job seeker category, if available and applicable<\/li>\n<li>a work visa after obtaining a qualifying offer and sponsor<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Employees<\/h3>\n\n\n\n<p>If you will perform actual employment in Korea, an <strong>E-series work visa<\/strong> may be more appropriate, depending on the occupation.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Students<\/h3>\n\n\n\n<p>For degree study or language training, this is not the right visa. Consider:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>D-2<\/strong> for degree study<\/li>\n<li><strong>D-4<\/strong> for general training\/language study where applicable<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Spouses\/partners and children<\/h3>\n\n\n\n<p>This is generally not the right initial route for family members. Family options, if any, depend on the principal applicant\u2019s status and duration.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Researchers<\/h3>\n\n\n\n<p>Research-focused entrants may need a different category, such as a relevant <strong>E-series<\/strong>, <strong>D-series<\/strong>, or institutional route depending on the project.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Digital nomads<\/h3>\n\n\n\n<p>Not appropriate. Remote work on a trainee visa is risky unless clearly permitted and incidental. Korea has separate policies for work-related stays.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Founders\/entrepreneurs and investors<\/h3>\n\n\n\n<p>Not suitable. Consider relevant entrepreneur or investment routes.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Retirees<\/h3>\n\n\n\n<p>Not applicable.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Religious workers<\/h3>\n\n\n\n<p>Not suitable. Korea has separate religious\/work categories.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Artists\/athletes<\/h3>\n\n\n\n<p>Not suitable unless the true purpose is approved technical training under D-3-12, which is uncommon.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Transit passengers<\/h3>\n\n\n\n<p>Not applicable.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Medical travelers<\/h3>\n\n\n\n<p>Use the relevant short-term medical treatment route.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Diplomatic\/official travelers<\/h3>\n\n\n\n<p>Use diplomatic\/official categories.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Quick suitability table<\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table>\n<thead>\n<tr>\n<th>Applicant type<\/th>\n<th style=\"text-align: right;\">Suitable for D-3-12?<\/th>\n<th>Better alternative<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Tourist<\/td>\n<td style=\"text-align: right;\">No<\/td>\n<td>Visa waiver \/ C-3<\/td>\n<\/tr>\n<tr>\n<td>Business visitor<\/td>\n<td style=\"text-align: right;\">Usually no<\/td>\n<td>C-3 business-type route<\/td>\n<\/tr>\n<tr>\n<td>Regular employee<\/td>\n<td style=\"text-align: right;\">Usually no<\/td>\n<td>Relevant E-series work visa<\/td>\n<\/tr>\n<tr>\n<td>Degree student<\/td>\n<td style=\"text-align: right;\">No<\/td>\n<td>D-2<\/td>\n<\/tr>\n<tr>\n<td>Language student<\/td>\n<td style=\"text-align: right;\">No<\/td>\n<td>D-4<\/td>\n<\/tr>\n<tr>\n<td>Industrial\/technology trainee<\/td>\n<td style=\"text-align: right;\">Yes<\/td>\n<td>D-3-12 if host and program qualify<\/td>\n<\/tr>\n<tr>\n<td>Spouse\/dependent<\/td>\n<td style=\"text-align: right;\">Usually no as principal route<\/td>\n<td>Dependent\/family route if available<\/td>\n<\/tr>\n<tr>\n<td>Entrepreneur<\/td>\n<td style=\"text-align: right;\">No<\/td>\n<td>Startup\/business route<\/td>\n<\/tr>\n<\/tbody>\n<\/table><\/figure>\n\n\n\n<h1 class=\"wp-block-heading\">3.

Official visa classification and naming<\/h1>\n\n\n\n<h2 class=\"wp-block-heading\">Official classification<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Visa class:<\/strong> D-3<\/li>\n<li><strong>Subclassification:<\/strong> D-3-12<\/li>\n<li><strong>Common English name:<\/strong> Industrial Trainee (Technology)<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Program name<\/h2>\n\n\n\n<p>The umbrella program is generally <strong>Industrial Training<\/strong> under the D-3 category.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Internal streams<\/h2>\n\n\n\n<p>The D-3 class has had multiple subcodes over time. Exact naming and sub-stream publication may vary by mission or the Visa Navigator database.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Related categories people confuse it with<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>D-2<\/strong>: student\/degree study<\/li>\n<li><strong>D-4<\/strong>: general training\/language training<\/li>\n<li><strong>E-series visas<\/strong>: employment categories<\/li>\n<li><strong>C-3<\/strong>: short visits\/business\/tourism<\/li>\n<li><strong>D-10<\/strong>: job seeking\/start-up preparation in some contexts<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Old vs current naming<\/h2>\n\n\n\n<p>The umbrella D-3 category is longstanding, but <strong>subcategory labeling and public-facing descriptions can change<\/strong>. Some missions may refer to the category only broadly as \u201cIndustrial Training\u201d without clearly displaying \u201cD-3-12.\u201d<\/p>\n\n\n\n<blockquote>\n<p><strong>Common Mistake:<\/strong> Assuming a generic \u201ctrainee\u201d invitation automatically means D-3-12. The exact subcategory should be confirmed by the Korean host and the consular post.<\/p>\n<\/blockquote>\n\n\n\n<h1 class=\"wp-block-heading\">5. Eligibility criteria<\/h1>\n\n\n\n<p>Because D-3-12 is a specialized category, eligibility is heavily driven by the <strong>host organization and training plan<\/strong>. Publicly available official guidance is more limited than for tourist visas, so applicants should verify mission-specific instructions.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Core eligibility factors<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">1. Genuine training purpose<\/h3>\n\n\n\n<p>You must be entering primarily for <strong>technology\/industrial training<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Korean host\/sponsor<\/h3>\n\n\n\n<p>You will usually need a Korean company or institution that:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>is legally established<\/li>\n<li>is eligible to host the trainee<\/li>\n<li>can issue supporting documents<\/li>\n<li>can explain the training content, duration, and supervision<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">3. Training plan or invitation<\/h3>\n\n\n\n<p>Expect a need for:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>invitation letter<\/li>\n<li>training schedule<\/li>\n<li>program outline<\/li>\n<li>host business registration\/corporate documents<\/li>\n<li>possibly proof of necessity and capacity to train<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">4. Passport validity<\/h3>\n\n\n\n<p>You need a valid passport. Many missions prefer enough validity to cover intended stay plus buffer, though exact minimums can vary.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">5. Immigration admissibility<\/h3>\n\n\n\n<p>You must not be barred for reasons such as:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>past immigration violations<\/li>\n<li>security concerns<\/li>\n<li>serious criminal issues<\/li>\n<li>document fraud<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">6. Financial support<\/h3>\n\n\n\n<p>The applicant or sponsor must usually show ability to cover:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>living costs<\/li>\n<li>travel costs<\/li>\n<li>stay-related costs<\/li>\n<li>possibly training support arrangements<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">7. Compliance with local embassy rules<\/h3>\n\n\n\n<p>Consulates may impose additional procedural requirements such as:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>local residency jurisdiction<\/li>\n<li>document translation<\/li>\n<li>appointment attendance<\/li>\n<li>mission-specific forms<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Nationality rules<\/h2>\n\n\n\n<p>There is <strong>no single publicly universal D-3-12 checklist for all nationalities<\/strong>. Rules can vary by:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>nationality<\/li>\n<li>country of application<\/li>\n<li>local Korean mission practice<\/li>\n<li>whether a <strong>Visa Issuance Confirmation Number<\/strong> is used<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Age<\/h2>\n\n\n\n<p>No clearly universal public age threshold appears consistently for D-3-12. However:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>applicants must be legally able to undertake the training arrangement<\/li>\n<li>minors would be unusual and may require extra consent and scrutiny<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Education \/ experience<\/h2>\n\n\n\n<p>This can vary by the host and training content. Some hosts may require:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>relevant educational background<\/li>\n<li>employment history<\/li>\n<li>technical relevance<\/li>\n<\/ul>\n\n\n\n<p>If a mission or sponsor requests these, they become practically essential.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Language<\/h2>\n\n\n\n<p>A universal Korean-language requirement is <strong>not clearly published<\/strong> for D-3-12. However, practical ability in:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Korean, or<\/li>\n<li>English, or<\/li>\n<li>another training language<\/li>\n<\/ul>\n\n\n\n<p>may matter for the host\u2019s approval and immigration credibility.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Sponsorship \/ invitation \/ job offer<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Sponsorship\/invitation:<\/strong> Usually yes<\/li>\n<li><strong>Job offer:<\/strong> Not necessarily in the normal employment sense<\/li>\n<li><strong>Training acceptance:<\/strong> Usually essential<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Funds \/ accommodation \/ onward travel<\/h2>\n\n\n\n<p>These may be requested, including:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>bank statements<\/li>\n<li>sponsor support letter<\/li>\n<li>accommodation details<\/li>\n<li>itinerary<\/li>\n<li>return or onward flight planning<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Health \/ character \/ biometrics<\/h2>\n\n\n\n<p>Depending on nationality, length of stay, and mission practice, applicants may need:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>criminal record documentation<\/li>\n<li>health-related documents<\/li>\n<li>TB screening in some contexts<\/li>\n<li>biometrics or identity verification<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Local registration rules in Korea<\/h2>\n\n\n\n<p>Anyone staying long enough may need:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Alien Registration<\/strong> \/ Residence Card procedures<\/li>\n<li>address reporting<\/li>\n<li>immigration updates if details change<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Quota\/caps\/ballots<\/h2>\n\n\n\n<p>No public lottery-style system is generally associated with D-3-12.

FAQs<\/h1>\n\n\n\n<h2 class=\"wp-block-heading\">1. Is D-3-12 a work visa?<\/h2>\n\n\n\n<p>No. It is a training-based status, not a general employment visa.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">2. Can I get paid on D-3-12?<\/h2>\n\n\n\n<p>Payment structure is sensitive. A stipend or supported training arrangement may be possible, but ordinary employment-style salary can raise category issues.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">3. Can I work part-time elsewhere?<\/h2>\n\n\n\n<p>Usually no.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">4. Can I freelance online from Korea?<\/h2>\n\n\n\n<p>Generally risky and likely outside the visa\u2019s purpose unless specifically authorized.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">5. Do I need a Korean company sponsor?<\/h2>\n\n\n\n<p>Usually yes, or another qualifying Korean host.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">6. Can I apply without an invitation letter?<\/h2>\n\n\n\n<p>Practically, that would be very difficult for this category.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">7. Is there a minimum bank balance?<\/h2>\n\n\n\n<p>No single universally published figure is consistently available for D-3-12. Show credible funding.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">8. Do I need a police certificate?<\/h2>\n\n\n\n<p>Sometimes. It depends on mission practice and case specifics.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">9. Do I need a medical exam?<\/h2>\n\n\n\n<p>Possibly, depending on mission and nationality.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">10. Is there an age limit?<\/h2>\n\n\n\n<p>No clearly universal public age rule is consistently published for D-3-12.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">11. Can students use this visa for internships?<\/h2>\n\n\n\n<p>Only if the activity clearly fits this trainee category. Otherwise another visa may be needed.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">12. Can I bring my spouse?<\/h2>\n\n\n\n<p>Not automatically. Family eligibility is limited and case-specific.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">13. Can my child study in Korea if accompanying me?<\/h2>\n\n\n\n<p>That depends on whether the child can lawfully accompany you under an appropriate status.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">14. Can I convert D-3-12 to an E-series work visa?<\/h2>\n\n\n\n<p>Sometimes, if you fully qualify and immigration permits a change of status.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">15. Does time on D-3-12 count toward permanent residency?<\/h2>\n\n\n\n<p>Usually not directly in a straightforward way. It is not a standard PR-track status.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">16. How long does processing take?<\/h2>\n\n\n\n<p>There is no universally published D-3-12 standard across all missions. Apply early.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">17. Is an interview mandatory?<\/h2>\n\n\n\n<p>Not always, but it can be required.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">18. Can I apply from a country where I am not a citizen?<\/h2>\n\n\n\n<p>Sometimes, if you are legally resident there and the mission accepts third-country applications.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">19. What if my sponsor changes after issuance?<\/h2>\n\n\n\n<p>Do not assume you can proceed unchanged. Contact immigration; a new approval may be needed.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">20. Can I arrive before the training start date?<\/h2>\n\n\n\n<p>Often yes within visa validity, but the timing should still make sense and fit the documents.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">21. Can I stay after training ends to travel?<\/h2>\n\n\n\n<p>Not automatically. Your permitted stay remains governed by your status and immigration record.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">22. What if I overstay by a few days?<\/h2>\n\n\n\n<p>Even a short overstay can create fines and future visa trouble.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">23. What if my passport expires during my stay?<\/h2>\n\n\n\n<p>Renew it and update immigration records as required.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">24. Do I need health insurance?<\/h2>\n\n\n\n<p>Very likely advisable and sometimes required in practice, especially for long stays.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">25. What if my bank statement has one large recent deposit?<\/h2>\n\n\n\n<p>Explain it with evidence.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">26. Can the company just write that I am a trainee even if I will really work?<\/h2>\n\n\n\n<p>No. That would be misrepresentation and can cause refusal or later penalties.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">27. Is D-3-12 the same as D-4 training?<\/h2>\n\n\n\n<p>No. D-3 and D-4 serve different purposes under Korea\u2019s immigration system.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">28. Can I change accommodation after arrival?<\/h2>\n\n\n\n<p>Usually yes, but address reporting obligations may apply.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">29. Are same-sex spouses recognized as dependents under this route?<\/h2>\n\n\n\n<p>Do not assume so. Verify directly with Korean authorities for your circumstances.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">30. If refused, can I immediately reapply?<\/h2>\n\n\n\n<p>Yes in many cases, but only after fixing the actual reason for refusal.<\/p>\n\n\n\n<h1 class=\"wp-block-heading\">36.
