Form I-131 Explained: Advance Parole and Travel Documents

Quick answer: Form I-131, Application for Travel Documents, is the USCIS form for permission to leave the United States and come back without losing ground on an immigration case or a green card. It covers several documents, and the three most people need are advance parole (for a pending green card, asylum or initial TPS application), a reentry permit (for green card holders who will be abroad for a year or more), and a refugee travel document (for refugees and asylees). Which one you need depends entirely on your status, so start there.

Key takeaways

• If your Form I-485 is pending and you leave the U.S. without advance parole, USCIS generally treats the I-485 as abandoned. The exceptions are narrow and listed below.
• A green card holder does not need a "travel permit" for ordinary trips. The green card is the reentry document. A reentry permit is for absences of a year or more.
• A reentry permit is generally valid for 2 years and cannot be extended. You must be in the U.S. when you file it and when you give biometrics.
• A refugee travel document is valid for 1 year and cannot be extended either.
• Advance parole does not guarantee you will be let back in. CBP decides at the port of entry, every time.

All of the rules on this page come from the Form I-131 page on USCIS.gov and the form's instructions (edition 01/20/25). Check the edition date there before you file, because USCIS can reject a filing made on an edition it no longer accepts.

What exactly does Form I-131 do?

Form I-131 asks USCIS for a document that lets you travel and return without abandoning a pending case or your permanent residence. It is one form, but it produces different documents for different people:

Only one of these fits you at a time. If you are in the middle of adjustment of status, you are almost certainly asking about advance parole.

Is there a "travel permit" for green card holders?

Not for normal trips. If you are a green card holder going abroad for less than a year, your green card and passport are what you travel on. USCIS says temporary or brief travel usually does not affect permanent resident status (International Travel as a Permanent Resident).

What people usually mean by a "travel permit" or "green card travel permit" is the reentry permit, and it is for longer absences:

• When you need one: USCIS advises applying before you go if you plan to be outside the U.S. for longer than a year. Without one, a long absence can be treated as abandoning your residence.
• How long it lasts: generally 2 years from the date it is issued. If you have spent more than 4 of the last 5 years outside the U.S. since becoming a resident, USCIS limits it to 1 year, with a few exceptions (for example, government-ordered travel). A conditional resident's permit can't run past the date the conditional status expires.
• No extensions: USCIS will not extend a reentry permit. If you stay out longer than it covers, the usual route back is a returning resident (SB-1) visa from a U.S. consulate, which means proving eligibility again and a medical exam.
• You must be here to apply: you have to be physically in the United States when you file and when you complete biometrics. Plan your filing backwards from your departure date so the biometrics appointment comes first.
• Picking it up abroad: when you file, you can ask for the permit to be sent to a U.S. embassy, consulate or USCIS international office to collect, though not every post offers this.

Citizenship is a separate clock: a reentry permit protects your green card, not your naturalization timeline. An absence of a year or more generally breaks the continuous residence needed to apply for citizenship, and an absence of six months or more may disrupt it. If you plan to be away for a year or more and want to protect that, look at Form N-470.

What is advance parole, in plain English?

Advance parole is permission, granted before you leave, to come back and ask to be paroled into the United States. It exists so that someone with a pending case can travel without that case being treated as abandoned.

The rule that makes it matter: if you have filed Form I-485 and you leave the U.S. without first getting advance parole, USCIS will generally consider the I-485 abandoned. That can mean starting over, or worse.

Who can skip it: the I-131 instructions list the classifications that generally do not abandon a pending I-485 by traveling without advance parole, as long as the person stays eligible for and would be admissible in that classification when they return:

• H-1 workers and their H-4 spouses and children
• L-1 intracompany transferees and their L-2 spouses and children
• K-3 spouses and K-4 children of U.S. citizens
• V-1 spouses and V-2/V-3 children of permanent residents

The catch is in the fine print. You must come back with a valid H, L, K or V visa in your passport. If yours has expired, you need a new one from a U.S. consulate before you return, and any gap in status makes the exception harder to rely on. If you are unsure whether you fit, get advance parole anyway, or ask an immigration attorney before you book.

Don't skip this: if your I-485 is pending and you don't clearly fall into one of those classifications, do not leave the U.S. until the advance parole document is approved and in your hands. More filing pitfalls like this are in Common Immigration Application Mistakes.

What advance parole does not do: the instructions are blunt that an advance parole document does not entitle you to parole and does not guarantee it. Each time you present it, CBP makes a new decision about whether to parole you back in.

Do I need a letter of explanation with Form I-131?

It depends on why you are applying. For advance parole filed from inside the U.S., the instructions ask for a copy of any USCIS document showing your current status, plus one of a list of items. The two that matter most:

• If you are filing the I-131 together with your I-485, you do not need an explanation of why you need advance parole.
• If you are filing the I-131 separately, after your I-485, a copy of your I-485 receipt notice can serve as the evidence.
• Everyone else asking for advance parole from inside the U.S. provides an explanation or other evidence showing the circumstances that justify it.

There is no official template for that explanation. Keep it short and factual: who you are, what is pending, where you are going, the dates, the reason for the trip, and copies of anything that supports it (a letter about a sick relative, a conference invitation, a wedding invitation). Other document types have their own rules. A refugee who files from abroad, for example, must explain why they did not apply before leaving.

How do I get emergency advance parole?

If you have an urgent reason to travel and can't wait for normal processing, USCIS lets you request emergency advance parole at a field office. According to the USCIS emergency travel page, you ask for an appointment by calling the USCIS Contact Center at 800-375-5283 (TTY 800-767-1833), by booking through My Appointment, or by secure message in your USCIS online account. Bring:

• A completed and signed Form I-131
• Evidence that you are eligible for the travel document
• Proof of the urgent need to travel, such as a doctor's letter or a death certificate
• Two passport-style photos
• Certified English translations of anything not in English

Approval is not guaranteed, and it is not a way to skip the queue for a planned trip.

How long does an I-131 take to process?

There is no single answer. It depends on the document you ask for and the office handling it, and it changes with USCIS workload. The only reliable number is the range USCIS publishes on its Check Case Processing Times page for your form, category and office.

A few patterns that hold regardless of the current numbers:

• Advance parole filed with an I-485 often moves with the adjustment case, but the two are not guaranteed to move in lockstep.
• A standalone advance parole request, filed after the I-485, runs on its own timeline.
• A reentry permit needs a biometrics appointment before you leave, so the appointment date, not the decision date, is usually what controls when you can go.
• If you are asked to come in for biometrics, your case status will usually update to Case Was Updated To Show Fingerprints Were Taken afterwards.

Why the published ranges and real-world waits can drift apart is covered in Why Your I-131 Wait Time Doesn't Add Up.

What should I have ready before I file?

Here's a working checklist for advance parole, since that is what most pending-case applicants need:

• Confirm your underlying case (I-485, asylum or initial TPS) is pending, or that you are filing the I-485 at the same time.
• Two passport-style photos that meet the current USCIS specifications.
• A copy of your government-issued photo ID.
• A copy of your I-485 receipt notice (Form I-797C) if you are filing the I-131 separately.
• An explanation of the trip and supporting documents, if you are not an adjustment applicant (see the letter section above).
• The current filing fee from the USCIS fee schedule. Fees change, and the wrong amount gets a package rejected.
• The current edition of the form, downloaded from USCIS.gov on the day you file.

If you are deep in adjustment of status already, this sits inside a much longer list. The full picture is in I-485 Checklist: Every Supporting Document.

What happens after USCIS approves my I-131?

You receive the document itself. For advance parole that is Form I-512 or I-512L, or advance parole printed on a combination card with your work permit. It shows how long it is valid and how many entries it allows. You present it to a Customs and Border Protection officer when you come back.

On the way back in:

• CBP makes the final call at the border, even with an approved document in hand.
• If your I-485 is still pending, carry copies of your receipt notices and the advance parole document.
• A reentry permit is checked alongside your green card, and a long absence can draw closer questions about where you actually live.

If something happens to your case while you are abroad, such as an approval, a request for evidence or an interview notice, it arrives by mail at the address USCIS has on file. MyCheck watches your receipt number and tells you in the app and by email when the status changes, so a request for evidence doesn't sit unseen in a mailbox you can't reach. Tracking one case is free.
