What documents does a green card holder need to reenter the US
Use the free tool — Travel Doc Check
Who this page is for
You have a green card (lawful permanent resident card) and you are flying internationally, then coming back to the US. Maybe you are traveling alone, with kids, or for a long stay. This page tells you what to check — not what the rule definitely is, because rules vary by nationality and change.
Two passports, two sets of rules
Your green card does not replace your passport. You still travel on your own country's passport, and the visas you need abroad follow that passport's nationality — not your US residence.
- Check the passport validity rule for your outbound destination. Many countries deny entry if your passport expires within three to six months of your stay — this is the rule that catches the most travelers. See the US State Department's country pages for your specific destination.
- If your passport's expiry date is close to your travel dates, plan to renew before you fly. Airlines can deny boarding over this.
Your green card is what brings you home
To reenter the United States, you need your green card (or the travel document that replaces it if you're mid-renewal). Carry it with you — do not pack it in checked luggage.
This page is not immigration legal advice. If your card is expired, lost, or you're unsure whether it's still valid for travel, confirm with the agency before you fly.
Long trips abroad: the reentry permit question
If you plan to be outside the US for an extended period, a reentry permit may be relevant — it's a document some green card holders get before a long trip. This page cannot tell you if you need one or how long that takes. Confirm current requirements and processing times directly with the agency before you plan a long absence.
Traveling with children who hold green cards
If a child is traveling without both parents, some countries require a notarized consent letter at the border, in addition to any US document questions. See the State Department's page on children's travel to check the practice for your trip.
If your trip includes a US domestic flight
If you'll fly domestically before or after your international leg, remember REAL ID: since May 2025, US domestic flights require a REAL ID-compliant license (or a passport) — the star on the license is what matters now. See TSA's REAL ID page.
What to do next
Rules like these depend on your nationality, your card's status, and your exact dates — not on a generic list. The free Travel Doc Check tool reads the details of your own trip (who's traveling, what documents you hold, where you're going and when) and gives you a checklist with the official link for each item, so you know exactly what to verify and where. Nothing you type is stored.
