If you are a permanent or conditional permanent resident who has been outside the U.S. for one year or longer, apply for a re-entry permit before you travel. Use Form I-131 - Application for Travel Document. For permanent residents, the re-entry permit is valid for two years from the date of issue.
To apply for Advance Parole, you must file Form I-131: Application for Travel Document with U.S. Citizenship and Immigration Services (USCIS). Green card applicants looking to travel abroad for any reason must obtain Advance Parole before leaving the United States.
Each line on the back of the green card contains 30 characters. The green card number is located in the last 13 characters of the first line, followed by two space holders. To be exact, the green card number is the characters for digits 16-28, followed by “>>.”
A travel document lets the U.S. government know about your travel plans. This is for anyone who is not a U.S. citizen but is living in the USA. You can use a travel document instead of a visa as proof of travel authorization. You must get your travel document before you leave the country.
Ing to USCIS data from 2023, the average processing time for Form I-131 (Application for Travel Document) varies between 3 to 7 months, depending on the service center handling the case and the specific category (e.g., refugee travel document, re-entry permit).
You must be a lawful permanent resident (green card holder) or a conditional lawful permanent resident (conditional green card holder). You must have the intention to leave the United States temporarily. You must file a Form I-131 and prove supporting documents (your immigration lawyer can file this for you).
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).
If You Need to Travel Generally, if you have a pending Form I-485 and you leave the United States without an advance parole document, you will have abandoned your application. For further information, see our Travel Documents page.
The travel document usually arrives within 150 days (sometimes longer) after submitting your application. You can't leave the country until you have your approved travel document in hand, so you should expect to spend the 3–5 months after submitting your green card application in the United States.
You do not need a reentry permit if you will be outside the United States for less than 1 year. If you have been outside the United States for less than 1 year, you may use your Permanent Resident Card (Form I-551) as your travel document.
