What documents do I need to travel outside the United States?
In general, you will need to present a passport from your country of citizenship or your refugee travel document to travel to a foreign country. In addition, the foreign country may have additional entry/exit requirements (such as a visa). For information on foreign entry and exit requirements, see the Department of State’s webpage.
What documents do I need to present to reenter the United States?
If seeking to enter the United States after temporary travel abroad, you will need to present a valid, unexpired “green card” (Form I-551, Permanent Resident Card). When arriving at a port of entry, a U.S. Customs and Border Protection Officer will review your permanent resident card and any other identity documents you present, such as a passport, foreign national I.D. card or U.S. Driver’s License, and determine if you can enter the United States. For information pertaining to entry into the United States, see U.S. Customs and Border Protection’s webpage.
Does travel outside the United States affect my permanent resident status?
Permanent residents are free to travel outside the United States, and temporary or brief travel usually does not affect your permanent resident status. If it is determined, however, that you did not intend to make the United States your permanent home, you will be found to have abandoned your permanent resident status. A general guide used is whether you have been absent from the United States for more than a year. Abandonment may be found to occur in trips of less than a year where it is believed you did not intend to make the United States your permanent residence. While brief trips abroad generally are not problematic, the officer may consider criteria such as whether your intention was to visit abroad only temporarily, whether you maintained U.S. family and community ties, maintained U.S employment, filed U.S. income taxes as a resident, or otherwise established your intention to return to the United States as your permanent home. Other factors that may be considered include whether you maintained a U.S. mailing address, kept U.S. bank accounts and a valid U.S. driver’s license, own property or run a business in the United States, or any other evidence that supports the temporary nature of your absence.
