What Is a Re-Entry Permit and When Do You Need One?

A re-entry permit is a travel document from U.S. Citizenship and Immigration Services (USCIS) that lets a green card holder stay outside the United States for up to two years without being treated as having given up permanent residence. You need one if you plan to be abroad for a year or longer, and it is worth having for any trip between six months and a year. With the permit in hand, you skip the returning resident visa process at a U.S. embassy, which is slower and much harder to win.

Who Needs One

Both lawful permanent residents and conditional permanent residents can apply. If you hold a green card and expect to be outside the country for a year or more, get the permit before you leave. Your green card alone will not get you back in after that long an absence.¹

For trips between six months and a year, the permit is not required. You can re-enter on your green card, but Customs and Border Protection will ask more questions, and officers can find that you abandoned status even on shorter trips.² Carrying a permit through that window tells the officer you planned the absence and always intended to come back.

What the Permit Actually Protects Against

The risk the permit addresses is an abandonment finding. USCIS does not apply a single time limit; officers weigh the whole picture, including:³

How long you were away. Trips over a year raise the strongest concerns, but shorter absences can still trigger a finding if other factors point the wrong way.
Why you traveled. Caring for a sick relative reads differently than relocating for a permanent overseas job.
Your U.S. ties: tax filings, property, a driver’s license, bank accounts, family in the country, ongoing employment.
Your foreign ties: property abroad, foreign employment, voting in foreign elections, running for office in another country.

One filing choice can wreck a case on its own. Claiming “nonresident alien” status on a U.S. tax return to lower your bill creates a rebuttable presumption that you have abandoned permanent residence. Other evidence can overcome it, but you start in a hole.³

A re-entry permit is one strong piece of evidence in your favor. It is not a shield. Without it, an absence over a year almost always triggers the presumption that you left for good.⁴

How To Apply

You file Form I-131, Application for Travel Documents, with USCIS.⁵ The form asks for your identifying information, Alien Registration Number, U.S. address, and travel history since you became a permanent resident. You submit copies of your green card, your passport biographical page, and two passport-style photos taken within 30 days of filing.⁶

You must be physically in the United States when you file. You cannot apply from abroad, so plan the timing. Leave before filing and you lose the option until you come back.¹

One useful option on the form: you can ask USCIS to send the approved permit to a U.S. embassy or consulate for pickup. That way you do not have to sit in the country for the full processing period. You still have to stay long enough for biometrics, but you can leave after that and collect the permit overseas.⁶ Not every post offers this service. Check with the specific embassy before you count on it.

The filing fee is $630 for a paper application, and that includes biometrics for applicants aged 14 through 79.⁷ You cannot file Form I-131 for a re-entry permit online. It has to go on paper to the designated USCIS Lockbox.⁵

Biometrics, Timing, and Expedites

After USCIS receives the application, you get a notice for a biometrics appointment, usually within a few weeks. You give fingerprints, a photograph, and a digital signature. You still have to be in the country for this step.

Processing times vary by office and change often. Check the USCIS processing times page for a current estimate. If your travel is fixed, file as early as you can. Waiting until the last minute is the most common avoidable mistake.

USCIS will consider an expedite request for Form I-131 in specific situations: a funeral or serious illness of a family member, urgent medical treatment, a pressing professional commitment, or another genuine emergency. Bring documentation: a death certificate, a doctor or hospital letter, or an employer letter on letterhead. A vacation does not qualify. USCIS also looks at whether you filed on time in the first place. If you waited until the eve of a planned trip, an expedite request is unlikely to succeed.⁸

How Long the Permit Lasts

A re-entry permit issued to a lawful permanent resident is valid for two years from the date of issuance. For a conditional permanent resident, it is valid for two years or until the date you must apply to remove conditions, whichever comes first.⁹

There is one important exception. If you have been outside the United States for more than four years in the aggregate, measured over the last five years or since you became a permanent resident (whichever is shorter), your permit is valid for one year instead of two.¹⁰ Long absences carry rising risk to your status, and the shorter validity reflects that.

Permits cannot be extended or renewed from abroad. If yours is running out and you need more time overseas, you have to come back, file a fresh application, and start again before you leave.¹ USCIS will also deny a new application if your prior permit is still valid, unless you turn the old one in or show it was lost.¹⁰

What the Permit Does Not Do

A re-entry permit protects your green card. It does not protect your path to citizenship. Naturalization requires continuous residence in the United States for a set period (typically five years, or three if you are married to a U.S. citizen). Any single absence of one year or more automatically breaks that continuity, even with a valid re-entry permit in hand the whole time.¹¹ Absences between six months and a year do not automatically break continuous residence, but they create a rebuttable presumption that it has been broken, shifting the burden to you.

Form N-470 is the separate application that can preserve continuous residence for naturalization purposes during a qualifying absence, and eligibility is narrow. Even with an approved N-470, you still need a re-entry permit for trips of a year or more. The two documents solve different problems.¹²

The permit also does not pause your U.S. tax obligations. A green card holder has to file a federal return reporting worldwide income every year, no matter where they live, until they formally surrender the green card by filing Form I-407.¹³ Skipping returns, or filing as a nonresident alien to cut your bill, does more than create a tax problem. It directly undercuts any argument that you meant to keep your permanent residence.

If the Permit Expires While You Are Abroad

If your permit runs out while you are still outside the country, you cannot renew from where you are, and your green card alone will not work for re-entry after more than a year. Your remaining option is a Returning Resident (SB-1) visa at the nearest U.S. embassy or consulate.⁴

The SB-1 is a much harder process than the permit was. You have to prove three things: that you had lawful permanent resident status when you left, that you always intended to return, and that your extended stay was caused by circumstances beyond your control.¹⁴ The last one is the sticking point. Staying longer for personal convenience does not count. Medical emergencies, work obligations, or a pandemic travel ban are the kinds of reasons that succeed.

The filing uses Form DS-117, your green card, your expired re-entry permit if you still have it, and documentation of your U.S. ties. An approved SB-1 leads into full immigrant visa processing, including a medical exam. Contact the embassy at least three months before you want to travel.¹⁴

Lost or Stolen Documents Abroad

If your green card or re-entry permit is lost or stolen while you are outside the country, you can apply for a boarding foil at a U.S. embassy or consulate using Form I-131A. It is a temporary travel document that gets you on a flight home. You pay the filing fee online before your embassy appointment and bring your passport, evidence of permanent resident status, and a police report. The boarding foil is not a replacement for the underlying document. Once you are back in the United States, you apply for the actual replacements through the normal channels.
