Anyone with a green card who needs to spend a long stretch outside the U.S. — to care for a family member, work, or study — runs into a question: does the card work to get back in? The regulation answers based on the length of the trip. The green card works as an entry document after a temporary absence of less than 1 year (8 CFR 211.1(a)(2)); for 1 year or more, USCIS points to the reentry permit (USCIS — travel documents).
What does the rule say about the green card as an entry document?
8 CFR 211.1(a)(2) accepts as an entry document "A valid, unexpired Form I-551, Permanent Resident Card, if seeking readmission after a temporary absence of less than 1 year." The next item, 211.1(a)(3), accepts "A valid, unexpired Form I-327, Permit to Reenter the United States" — which is the reentry permit (8 CFR 211.1).
What is the reentry permit?
According to USCIS, permanent or conditional residents should apply for a reentry permit "if they will be outside the United States for one year or more." And while it is valid, it "allows you to apply for admission to the U.S. without having to obtain a returning resident visa from a U.S. Embassy or Consulate" (USCIS — travel documents). In other words: with it, you apply for readmission without needing a returning resident visa from the consulate.
Who applies and when?
The application is filed using Form I-131. The regulation requires that the applicant "must file such application while in the United States" and be "in status as a lawful permanent resident or conditional permanent resident" (8 CFR 223.2(b)(1)). In other words: the application goes out before the trip, while you're in the U.S., and the following steps are in the form's instructions.
How long is it valid?
As a rule, "a reentry permit issued to a permanent resident shall be valid for 2 years from the date of issuance" (8 CFR 223.3(a)(1)). There is an exception: for those who, since becoming a resident or within the last five years (whichever is shorter), have been outside the U.S. for more than four years combined, validity is limited to one year (8 CFR 223.2(c)(2)).
What about U.S. citizenship?
These are separate rules. For naturalization, the regulation states that continuous absences between six months and one year break continuous residence "unless the applicant can establish otherwise," and that absences of one year or more break continuity (8 CFR 316.5(c)(1)). The text of 316.5 does not say that the reentry permit preserves residence for citizenship purposes. Anyone planning to file the N-400 in the coming years can check the requirements in the N-400 document checklist.
Checklist before a long trip
- Estimate how long you'll be away. Less than 1 year: the rule about the green card as entry document applies. 1 year or more: the reentry permit applies.
- File the I-131 before leaving, while you're in the U.S.
- Check your green card's expiration date — if it expires during the trip, the I-90 guide explains renewal.
- Keep the receipts and copies of your application.
- If your case is a pending application (not an already-approved green card), the document is different: see traveling with a pending immigration case.
