To legally live in another country from the US, you need a visa or residency permit issued by that country’s government, and the right one depends on why you’re going — a job, school, family, investment, retirement, or remote work. Every country writes its own rules, but the broad categories are similar, and the sequence is predictable: pick the category you qualify for, gather and authenticate your documents, apply through the destination country’s consulate or immigration authority, and then keep up with the compliance obligations that follow you across the border, including U.S. taxes.
Which Visa Category Fits Your Situation
Most countries sort foreign residents into a handful of standard categories. The one you qualify for determines the paperwork, the financial thresholds, and how much freedom you’ll have after you arrive.
- Work visas. Usually require a confirmed job offer, and often employer sponsorship. Some countries make the employer prove no local candidate was available. Expect to document your qualifications and experience.
- Student visas. Built around an acceptance letter from a recognized school, plus proof you can pay tuition and living costs for at least the first year without working.
- Family reunification visas. Available if a spouse, parent, or child is already a citizen or legal resident. The sponsoring relative generally has to meet an income threshold and document the relationship.
- Investment visas. Sometimes called golden visas. You commit a substantial sum through real estate, a business, or government bonds. Required amounts vary widely between countries.
- Retirement visas. For older applicants who won’t work. You’ll need to show stable pension income, savings, or investments, and comprehensive health insurance is almost always mandatory.
- Digital nomad visas. A newer category for remote workers employed by companies outside the host country. Income thresholds range from roughly $1,500 per month in some Latin American and African countries to $5,000 or more per month in places like Dubai or Iceland. These usually run one to two years and don’t lead to permanent residency on their own.
Whether You Can Keep Your U.S. Citizenship
U.S. law does not require you to choose between American citizenship and a foreign one, and naturalizing in another country carries no risk to your U.S. citizenship. You can carry both passports. The catch is that dual nationals owe allegiance to both countries and must obey each one’s laws, and you must use your U.S. passport to enter and leave the United States even if you also hold a foreign one.1U.S. Department of State. Dual Nationality
Some countries don’t recognize dual citizenship at all and will require you to renounce your original nationality to naturalize. Check the destination’s rules before you assume you can hold both.
Documents You’ll Need to Gather
This is where people underestimate the time and cost. Most immigration applications ask for some mix of a valid passport, birth certificate, marriage certificate if applicable, educational credentials, financial records, and a police clearance.2U.S. Department of State. Step 7 – Collect Civil Documents Each one generally has to be an original or certified copy, translated by a certified translator if it’s not in the destination country’s language, and authenticated for international use.
Apostilles and Authentication
If the country you’re moving to belongs to the Hague Apostille Convention (currently 129 countries), your documents need an apostille rather than the older legalization process.3Hague Conference on Private International Law. Convention of 5 October 1961 – Status Table An apostille is a standardized certificate confirming your document is genuine. In the U.S., the Secretary of State in the state where the document originated issues it. Fees vary by state but often run around $10 per document. If the destination isn’t a Hague member, you’ll need full consular legalization instead, which has more steps and costs more.
The FBI Background Check
Nearly every country wants a criminal background check. For Americans, that usually means an Identity History Summary from the FBI, which costs $18 and requires fingerprints submitted electronically or by mail.4Federal Bureau of Investigation. Identity History Summary Checks Frequently Asked Questions The FBI doesn’t expedite requests, so start early. You may also need police certificates from other countries where you’ve lived for an extended period, and these certificates typically expire after two years.2U.S. Department of State. Step 7 – Collect Civil Documents
Proving You Can Support Yourself
Immigration authorities want confidence you won’t become a financial burden. Depending on the visa, you’ll be asked for bank statements, proof of income or pension, investment accounts, or a signed salary offer. Every country sets its own threshold, and falling short is one of the most common reasons applications get denied.
Currency Reporting When You Leave
If you’re carrying more than $10,000 in cash or monetary instruments out of the country, federal law requires you to report it to U.S. Customs and Border Protection. That threshold applies collectively to a family or group traveling together, not per person.5U.S. Customs and Border Protection. Money and Other Monetary Instruments Failing to report can trigger seizure and penalties.
For larger sums, most people use international bank transfers. Standard SWIFT transfers pass through one to three intermediary banks, each charging a fee. Total costs often run 1% to 4% of the transfer amount depending on the banks and exchange rates involved. Some newer services undercut traditional banks substantially, so compare options before moving a large balance.
How the Application Actually Runs
Once your documents are assembled, the process tends to follow the same arc: submit the application and pay the fee, attend an interview at the embassy or consulate if one is required, give biometric data like fingerprints and photos, and wait. Fees range widely — student and standard work visas may cost under a few hundred dollars, while investment and residency applications can reach several thousand.
Processing times catch people off guard. Student visas can clear in a few weeks. Work visas often take two to four months. Investment and residency applications can stretch past a year. Most authorities offer online tracking, and you should check it. Requests for additional documents are common, and slow responses can push you to the back of the queue or lead to denial.
U.S. Taxes Don’t Stop When You Leave
Americans moving abroad discover this too late more often than any other issue. The United States taxes its citizens on worldwide income regardless of where they live. If you’re a U.S. citizen or resident alien, you must file a federal return and report all taxable income from every source, even if you also owe tax on the same earnings to another country.6Internal Revenue Service. U.S. Citizens and Resident Aliens Abroad The U.S. is one of only two countries that taxes based on citizenship rather than residency.
The Foreign Earned Income Exclusion
The main relief is the Foreign Earned Income Exclusion, which lets you exclude up to $132,900 of foreign earned income from U.S. taxation for tax year 2026.7Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 To qualify, you must pass either the physical presence test — 330 full days in a foreign country during any 12-month period8Internal Revenue Service. Foreign Earned Income Exclusion – Physical Presence Test — or the bona fide residence test, which requires genuine residence in a foreign country for an uninterrupted period covering at least one full tax year.9Internal Revenue Service. Foreign Earned Income Exclusion – Bona Fide Residence Test You can also claim a foreign tax credit for taxes paid to another country to prevent double taxation on the same income.
Reporting Foreign Bank Accounts
Once you open a bank account overseas, reporting rules kick in and the penalties for ignoring them are steep. If the combined value of your foreign financial accounts exceeds $10,000 at any point during the year, you must file a Report of Foreign Bank and Financial Accounts (FBAR) with the Treasury by April 15, with an automatic extension to October 15.10Internal Revenue Service. Report of Foreign Bank and Financial Accounts (FBAR) Non-willful violations can reach $10,000 per account per year. Willful violations carry far higher penalties.
Separately, if you live abroad and your specified foreign financial assets exceed $200,000 on the last day of the tax year (or $300,000 at any point during the year) for single filers, you must also file Form 8938 under FATCA. The thresholds double for joint filers: $400,000 on the last day or $600,000 at any time.11Internal Revenue Service. Do I Need to File Form 8938, Statement of Specified Foreign Financial Assets FBAR and FATCA are separate filings with separate thresholds. You may owe both.
Social Security and Medicare After You Move
U.S. citizens can generally keep receiving Social Security payments while living abroad. If you’re not a U.S. citizen, benefits typically stop after six consecutive calendar months outside the country unless you qualify for a specific exception.12SSA.gov. SSA Payments Outside US The U.S. also maintains totalization agreements with about 30 countries, which prevent you from paying Social Security taxes to both systems and let you combine work credits toward benefit eligibility.13SSA.gov. U.S. International Social Security Agreements These cover most of Western Europe, Canada, Australia, Japan, South Korea, and several others. Move somewhere without an agreement and you could end up paying into two systems at once.
Medicare is a harder line. It generally will not pay for healthcare outside the United States, with only a handful of narrow emergency exceptions.14Medicare.gov. Medicare Coverage Outside the United States That includes Part D prescription drugs, routine doctor visits, and dialysis. If you’re living abroad permanently, plan on private international health insurance or enrollment in the host country’s system. Some expats keep paying Medicare premiums to preserve U.S. coverage for return trips, but that only pays off if you visit regularly or expect to move back.
Staying Legal After You Arrive
Getting the visa is only half the job. Staying legal means continuing to meet the conditions that got you in. On a work visa, that usually means working only for the sponsoring employer. Student visa holders must stay enrolled. Violating those conditions can revoke your status and bar future applications.
Track your expiration date closely. Renewal applications often need to be filed months in advance, and you’ll typically need updated financial records and proof you still meet the original eligibility rules. Many countries also require you to register changes of address, employment, or marital status locally. Missing those administrative steps is the kind of quiet compliance failure that surfaces later when you apply for permanent residency or citizenship.
If citizenship in the host country is the long-term goal, most nations require a minimum period of continuous physical presence, often five years or more, and extended absences can reset the clock. Compliance with local tax laws matters here too, since tax debts and evasion are common grounds for denial.
Renewing Your U.S. Passport From Abroad
Your U.S. passport stays your most important document overseas, and it will eventually expire. In most countries you must apply in person at the nearest U.S. embassy or consulate; a limited number of posts allow mail-in renewals. You’ll submit your expiring passport as proof of citizenship and provide a new passport photo.15U.S. Department of State. Apply for a Passport Outside the United States Don’t cut it close. Many countries require at least six months of remaining validity for continued residence, and embassy processing times can be unpredictable.
If You Ever Renounce: The Exit Tax
For Americans who eventually renounce U.S. citizenship, there’s a financial reckoning worth knowing about even if you never plan to give up your passport. If your net worth is $2 million or more, or your average annual net income tax liability over the previous five years exceeds the inflation-adjusted threshold ($206,000 for 2025), you’re classified as a covered expatriate and subject to the expatriation tax.16Internal Revenue Service. Expatriation Tax It treats your worldwide assets as if sold on the day before you renounce, triggering capital gains taxes on the unrealized appreciation. That reality makes renunciation far more expensive than most people assume, and it belongs in your long-term planning long before you’d ever act on it.
