Keeping your green card — travel, taxes and renewal

Your green card is proof of permanent residency—but it does not mean you can ignore U.S. laws and simply live elsewhere indefinitely. The government can revoke or deny reentry based on abandonment of status, and the IRS still taxes your worldwide income every year. Your card itself also expires every 10 years. This guide covers the three pillars of keeping your permanent resident status intact: travel rules, tax compliance, and card renewal.

Travel Abroad: The 6-Month and 1-Year Rules

Extended stays outside the United States can trigger questions about your intention to keep U.S. residency. U.S. Customs and Border Protection (CBP) and USCIS apply specific thresholds based on how long you are gone.

Trips Under 6 Months

Absences of fewer than 180 days are generally considered temporary and raise no presumption that you have abandoned your residence. You should still be prepared to show that your trip was temporary—for example, by carrying evidence of U.S. ties like a lease, job letter, or bank statements—but a short trip alone will not jeopardize your status.

Trips Between 6 Months and 1 Year

Once you cross the 6-month threshold, USCIS may begin asking questions about whether you intend to maintain U.S. residence. An absence of more than 180 days makes you legally "seeking admission" upon reentry, meaning CBP officers can scrutinize you as if you were entering for the first time. They can question your intent and, if unconvinced, deny entry or hold you for further review.

To overcome this presumption, be ready to provide evidence such as: maintaining U.S. employment or a clear reason for the absence, holding a U.S. residence (home or apartment), keeping your family in the U.S., filing U.S. tax returns, and maintaining U.S. bank accounts and credit cards.

Trips of 1 Year or More

An absence of one year or longer creates a legal presumption that you have abandoned your permanent resident status. Your green card is considered invalid for reentry, and CBP will almost certainly deny you entry unless you have obtained a reentry permit beforehand.

Applying for a Reentry Permit Before You Leave

If you know you will be gone for longer than 6 months, apply for a reentry permit (Form I-131) before you depart. This document protects you from the presumption of abandonment and allows you to stay abroad for up to 2 years without your green card being invalidated.

How to Apply

1. File Form I-131 (Application for Travel Document) while you are physically present in the United States. You cannot file this form from abroad.
2. Pay the filing fee and biometrics fee (check USCIS for current amounts).
3. Attend a biometrics appointment at your local USCIS Application Support Center (ASC). This is required before you leave.
4. USCIS recommends filing at least 60 days before your planned departure to allow time for the biometrics appointment.
5. Once you have filed and completed your biometrics appointment, you may travel abroad. You do not need to wait for approval.

The reentry permit is typically mailed to you in the United States, but you can also request that USCIS send it to a U.S. embassy or consulate abroad for pickup. Check the USCIS website for current processing times for your service center, as these vary significantly.

Filing U.S. Taxes Every Year

The moment you become a lawful permanent resident (green card holder), the IRS treats you as a U.S. tax resident. This obligation continues every single year for as long as you hold the status, whether you are living in the United States or abroad.

Worldwide Income Reporting Requirement

As a green card holder, you must report all income earned worldwide to the IRS, regardless of where you live or where the income was earned. This includes wages, self-employment income, rental income, investment income, and income from any other source.

Filing Requirements and Deadlines

You must file Form 1040 (U.S. Individual Income Tax Return) each year by April 15, unless you qualify for an automatic extension. If your tax home and abode are both outside the United States, you automatically receive a two-month extension to June 15—but you still owe any taxes due by the April 15 deadline, even with the extension.

Your actual filing requirement depends on your income level. Consult IRS Publication 54 (Tax Guide for U.S. Citizens and Resident Aliens Abroad) or the IRS website to determine if your gross income meets the filing threshold for your filing status.

State Income Tax

Many U.S. states impose income tax on residents. If you earned income in the United States or maintained a permanent home in a state that has an income tax, you may also be required to file a state return. State tax rules vary—some states tax green card holders who live abroad; others do not. Check with your state's tax authority or a tax professional familiar with your situation.

Why Filing Matters for Your Status

Filing U.S. taxes is not just a legal obligation—it is evidence that you intend to maintain U.S. residency. Conversely, failing to file tax returns or filing a form claiming bona fide residency in a foreign country (Form 2555) can be used against you as evidence of abandoning your U.S. residence. If you are away for 6 months or longer and CBP questions your intent, unfiled tax returns will weaken your case.

Renewing Your Green Card Every 10 Years

Your permanent resident status does not expire—you are a permanent resident for life unless you formally renounce it or it is revoked. However, the physical green card itself expires every 10 years. The card is your official proof of status, and an expired card can cause serious problems.

Why You Must Renew the Card

An expired green card is no longer valid for international travel, employment verification, or proving your work authorization to employers. If your card has expired and you try to return to the United States from abroad, CBP will likely deny you reentry. An expired card also complicates Form I-9 employment eligibility verification.

How to Renew

File Form I-90 (Application to Replace Permanent Resident Card) with USCIS. You can file online or by mail. Form I-90 also covers replacing a green card that was lost, stolen, or damaged.

When to File

File within 6 months before your card expires or immediately if it has already expired. You cannot file more than 6 months in advance. If you file before the expiration date, your filing receipt extends your card's validity for an additional 36 months while your application is pending, even if your physical card expires in the meantime.

Fees and Processing Time

As of 2026, filing online costs $415; filing by mail costs $465. The biometrics fee is included. Processing times vary by USCIS service center but typically range from 8 to 13 months. Check the USCIS Processing Times tool for your specific service center before you apply.

Special Rules for Conditional Green Cards

If you received your green card through marriage to a U.S. citizen and were married for fewer than 2 years at the time of approval, or if you obtained it through a qualifying investment, you have a conditional green card valid for 2 years. Do not file Form I-90 to renew a conditional card. Instead, file Form I-751 (Petition to Remove Conditions on Residence) during the 90 days immediately before your card's second anniversary. Once your petition is approved, you will receive a standard 10-year green card, which you then renew using Form I-90.

Practical Tips for Travel and Renewal

• Always carry your valid green card and passport when traveling internationally. Do not travel with an expired or about-to-expire card.
• If your card expires while you are abroad, you may have difficulty reentering the United States. File Form I-90 before your trip if renewal is coming up.
• Keep copies of your green card, birth certificate, passport, and recent tax returns in a safe place. These are often needed to prove status.
• If you are planning a trip longer than 6 months, apply for a reentry permit at least 2-3 months in advance, accounting for processing delays.
• Track multiple absences. CBP does not reset the clock on January 1. If you take a 4-month trip, then a 3-month trip within the same 12 months, the combined 7 months may trigger scrutiny.
• Consult an immigration attorney if you have a complex travel history, criminal record, or are uncertain whether you have abandoned your residence.

What Happens at the Airport and Border

When you return to the United States, CBP officers at the airport, land border, or seaport have the authority to question you about your residence and travel history. If your trip was longer than 6 months, or if your card is expired, or if other factors suggest you may have abandoned your residence (such as selling your home, terminating employment, or failing to file taxes), you may face delays, interrogation, or denial of reentry.

CBP can require you to provide evidence of your intent to reside in the United States. Have documentation readily available: proof of U.S. employment, a lease or mortgage, bank statements, tax returns, and any other ties. If CBP determines you have abandoned your status, they can refuse you entry, seize your card, and place you in removal proceedings.

Key Takeaways

• Trips under 6 months are generally safe; trips between 6 months and 1 year require strong evidence of U.S. ties; trips over 1 year require a reentry permit obtained before departure.
• File U.S. tax returns every year on your worldwide income, regardless of where you live or earn the money.
• Renew your green card every 10 years, filing Form I-90 within 6 months of expiration.
• An expired green card does not end your status, but it prevents you from traveling and proving work authorization.
• If you have a conditional 2-year green card, file Form I-751 to remove conditions, not Form I-90.
• At any border, CBP can question your residence intent and deny reentry if they believe you have abandoned your status.
