Frequently Asked Questions
Can immigrants contribute to a Roth IRA?
Yes, if you have earned income in the U.S. and a valid SSN or ITIN, you can contribute to a Roth IRA regardless of visa status. For 2025, the contribution limit is $7,000 ($8,000 if age 50+), subject to income phase-outs starting at $146,000 (single) or $230,000 (married filing jointly). You cannot contribute more than your earned income for the year.
What is the PFIC rule and how does it affect immigrant investors?
PFIC stands for Passive Foreign Investment Company. If you invest in foreign mutual funds, ETFs registered outside the U.S., or certain foreign holding companies, the IRS applies punishing tax rates on gains and requires Form 8621. Most immigrants can avoid this by sticking to U.S.-registered ETFs like VTI and VXUS rather than buying ETFs registered in their home country.
Do I pay U.S. taxes on investment income if I’m on a visa?
If you are a resident alien (meet the substantial presence test — roughly 183 days per year in the U.S.), you pay U.S. taxes on worldwide income including investment income, the same as a citizen. Non-resident aliens pay U.S. tax only on U.S.-source income. Dividends from U.S. stocks are generally withheld at 30% for non-residents, reduced by tax treaty.
Can I collect Social Security if I worked in the U.S. but returned home?
If you worked in the U.S. long enough to earn 40 credits (typically 10 years), you can collect Social Security at retirement age even if you live abroad — except in certain countries. If you have fewer than 40 credits, totalization agreements with 30 countries allow you to combine U.S. and home-country credits to qualify.
What happens to my Roth IRA if I leave the U.S. permanently?
Your Roth IRA remains yours. You can keep it, continue managing it, and eventually take qualified distributions tax-free in retirement. However, contributions stop when you no longer have U.S. earned income. Some countries have tax treaties that recognize the Roth IRA’s tax-free status; others may tax distributions as ordinary income. Canada and the UK have favorable treaty treatment; most other countries do not.
