Foreigners can usually open a bank account abroad by visiting a local branch of a bank or, in some cases, by applying online or through international banks with multi-country services, but requirements vary widely depending on the country, the type of account, and the applicant's residency status. In most countries, the minimum required documents include a valid passport as proof of identity, a secondary form of ID such as a driver's license or national ID card, proof of address in the foreign country (often a utility bill, rental contract, or official letter in the applicant's name), and sometimes a visa, residence permit, or work permit demonstrating legal status. Many banks also ask for tax identification numbers from the applicant's home country and the host country, such as a Social Security Number (SSN) in the United States or an equivalent tax ID elsewhere, though some institutions may allow account opening without this initially while restricting certain features like interest or credit products. Additional documents that may be requested include proof of income or employment (pay stubs, employment letter, or tax returns), bank references or letters of recommendation from the applicant's existing bank, proof of source of funds to comply with anti-money-laundering regulations, and a detailed explanation of how the account will be used, especially when opening offshore accounts or accounts in countries with strict financial regulations. Some banks require documents to be translated into the local language, certified by a notary, or apostilled for international recognition, which can add time and cost to the application process, and applicants may need to appear in person at a branch for identity verification even if the initial application is submitted online. Expats and long-term residents generally find it easier to open accounts than tourists or short-term visitors because banks prefer clients with stable local addresses and income, and some countries require a minimum deposit or balance to activate or maintain an account, ranging from a nominal amount to several thousand dollars depending on the account type and institution. International banks and digital banks with expat-focused services, such as HSBC Expat, Citibank International, Wise (formerly TransferWise), Revolut, and N26, offer streamlined application processes, multi-currency accounts, and online banking in English, though their availability and features vary by country. It is advisable to research banks in advance, compare fees for account maintenance, foreign transactions, and ATM withdrawals, and confirm that the bank offers services in a language the applicant is comfortable with, because banking procedures, customer service quality, and digital tools can differ significantly from what expats are used to at home.
