Re-entry permit vs. advance parole: how to apply and when to use eachReentry permit vs. advance parole

Wang Law Firm, LLC · David Wang, Managing Attorney · Attorney-reviewed · Updated October 2026

In Chinese, a single common term (often rendered “return-to-America permit”) is used for two completely different documents, and this is where many people start to go wrong. A green card holder who will stay abroad for a long time needs a re-entry permit; a person whose I-485 adjustment of status is pending and who holds only a receipt notice needs advance parole to travel abroad. Both are requested from U.S. Citizenship and Immigration Services (USCIS) on Form I-131, but they differ in who qualifies, legal basis, filing requirements and risks.

This article is organized by “what status you have”: first the re-entry permit for green card holders, then advance parole for I-485 applicants, then travel while I-751 (removal of conditions) or N-400 (naturalization) is pending, and finally a table comparing the re-entry permit, advance parole, the I-797 extension receipt and the returning resident visa (SB-1), with a pre-departure checklist. Fees and processing times change, so this article does not give specific figures; check current USCIS publications. For how to look them up, see How to check filing fees and processing times.

Form I-131: one form, many uses

The current English title of I-131 is Application for Travel Documents, Parole Documents, and Arrival/Departure Records. As of October 2026, USCIS accepts the January 20, 2025 edition (01/20/25 edition): USCIS published the new edition in March 2025, and after the grace period ended, only this edition is accepted for applications postmarked on or after April 4, 2025. In the second half of 2025 USCIS also sought public comment on further revisions to I-131, so the form may still be updated. Before filing, confirm the currently accepted edition on the official USCIS I-131 page; an outdated edition may simply be rejected.

The new I-131 groups the application types at the beginning of the form. They mainly include: re-entry permit, refugee travel document, advance parole for a person in the United States, initial parole for a person outside the United States, re-parole, and others. This article covers only the two most commonly used: the re-entry permit and advance parole for a person in the United States. When completing the form, check only the one type that matches your situation. For item-by-item guidance, see Form I-131 explained.

Re-entry permit: for green card holders

Why you need it

The green card (Form I-551) can itself serve as an entry document, but under federal regulation 8 CFR 211.1(a)(2), this applies only to permanent residents returning to the United States after an absence of less than one year. A person who has been away for one year or more without a valid re-entry permit generally can no longer enter on the green card, will usually be presumed to have abandoned permanent resident status, and can only consider options such as the returning resident visa (SB-1). A person who has been away for more than six months but less than one year may also be asked whether they have abandoned residence; see Long absences for green card holders.

The legal basis for the re-entry permit (formally the Permit to Reenter the United States, Form I-327) is INA 223 and 8 CFR part 223. Under 8 CFR 223.3(d), a permanent resident with a valid re-entry permit who is otherwise admissible will not be found to have abandoned status based solely on the length of absence during the permit’s validity period. The re-entry permit can also be used as a travel document.

Who can apply

• Lawful permanent residents (LPRs), and two-year conditional permanent residents (8 CFR 223.2(b)(1));
• It is usually suited to people who plan to stay outside the United States continuously for one year or more, for example on an overseas work assignment, returning home to care for parents, or accompanying children studying abroad; people who expect a long absence of less than one year but worry about being questioned about abandoning residence can also discuss with an attorney whether to apply.

Validity period

• Generally two years, counted from the date of issuance (8 CFR 223.3(a));
• Conditional green card holders: valid for two years or until the date you must apply to remove conditions (file I-751 / I-829), whichever comes first;
• People who have spent a long time abroad: under 8 CFR 223.2(c)(2), if you have spent more than four years in total outside the United States during the past five years (or since becoming a permanent resident, whichever is shorter), the re-entry permit is generally issued for only one year. Limited exceptions include people abroad on U.S. government orders, working for an international organization in which the United States participates, professional athletes, and others;
• It cannot be extended (8 CFR 223.3(c)). To keep using one, you must return to the United States and reapply from inside the country;
• If you already hold a re-entry permit that is still valid, a new application will be denied unless you return it to USCIS or show that it was lost (8 CFR 223.2(c)(1)).

Filing and biometrics

1. File while you are in the United States. 8 CFR 223.2(b)(1) requires re-entry permit applicants to file while in the United States. Mailing or submitting online while you are abroad does not meet this requirement.
2. Complete biometrics in the United States. After filing, USCIS sends a biometrics appointment notice, and you must go to an Application Support Center (ASC) in the United States for fingerprints and a photo. If biometrics are not completed, the application may be denied. If your travel date is tight, you can include a written explanation and evidence with the filing to request an expedited biometrics appointment; whether to schedule it earlier is at USCIS’s discretion, so do not book tickets on that assumption.
3. You may depart after biometrics. Under 8 CFR 223.2(d), leaving the United States while the application is pending does not affect the re-entry permit application.
4. Choose where the document is delivered. You can have it mailed to a U.S. address, or select on the form to pick it up at a U.S. embassy or consulate abroad (or another overseas location listed on the form). If you choose overseas pickup, specify the city and confirm in advance that the embassy or consulate offers this service; if you choose a U.S. address, arrange for a reliable person to receive it and forward it safely.

A common arrangement is to allow enough time before departure to file in the United States and wait for biometrics, or to return to the United States to file, leave, and then come back for biometrics according to the notice. How to arrange it depends on your itinerary and the biometrics scheduling at the time.

What a re-entry permit does not solve

• It does not guarantee admission. On arrival, CBP still examines whether you are admissible, for example whether you have criminal issues or other grounds of inadmissibility.
• It does not completely rule out a finding of abandonment. 8 CFR 223.3(d) says you will not be found to have abandoned status “solely based on the length of absence”; if other evidence shows you have moved the center of your life out of the United States (for example, no residence in the United States, or filing U.S. taxes as a nonresident), you may still be challenged.
• It does not preserve the “continuous residence” required for naturalization. This is the most common misunderstanding. Under INA 316 and 8 CFR 316.5, a single absence of more than 6 months but less than one year is presumed to break continuous residence, and an absence of one year or more usually breaks it outright; the re-entry permit has no effect on this. Only people working abroad for the U.S. government, a qualifying U.S. company or an international organization, among others, may separately apply on N-470 to preserve continuous residence. You can check naturalization timing with the N-400 calculator.
• It does not affect ongoing immigration court proceedings. 8 CFR 223.2(f) provides that issuing a re-entry permit to a person in removal proceedings does not affect those proceedings.

Advance parole: for people with a pending I-485

Why you need it

Under 8 CFR 245.2(a)(4)(ii), leaving the United States while an I-485 adjustment of status application is pending generally causes the application to be treated as abandoned (abandonment); but if you obtained advance parole beforehand and are inspected and paroled on return, it is not treated as abandoned. The legal basis for advance parole is the parole authority in INA 212(d)(5)(A) and 8 CFR 212.5(f).

Who does not need advance parole (regulatory exceptions)

8 CFR 245.2(a)(4)(ii)(C) and (D) provide the following exceptions, under which departure does not cause the I-485 to be treated as abandoned:

• H-1B and L-1 holders: on return you still qualify for H or L status, return to the same employer to continue working, and hold a valid H or L visa (if a visa is required) and the original I-797 approval notice;
• H-4 and L-2 holders: your H-1 or L-1 spouse or parent still maintains that status, and on return you hold a valid H-4 or L-2 visa (if a visa is required) and still qualify for that status;
• K-3 and K-4 holders: on return you hold a valid K-3 or K-4 visa and still qualify for that status;
• V status holders: on return you can be admitted in V nonimmigrant status.

Note: if you have switched to working for another employer on a work permit, or your H/L status has lapsed, you may no longer qualify for this exception. Before departing, check your actual current status; if you are unsure, proceed as though you need advance parole.

In addition, I-485 applicants who are in removal proceedings in immigration court who leave the United States will have the application treated as abandoned, and this may result in termination of the proceedings (8 CFR 245.2(a)(4)(ii)(A)). In this situation you must see an attorney before departing.

How to apply and when you can travel

• You can file I-131 together with I-485, or file it separately while I-485 is pending;
• Filing does not mean you can travel. Under the I-131 instructions, if you leave the United States before the advance parole document is issued, the advance parole application is generally treated as abandoned. Wait until you have the document before traveling, and do not book nonrefundable travel before approval;
• In an emergency, you can request expedited processing following USCIS instructions, or make an appointment at a local office for an emergency travel document; whether to grant it is up to USCIS;
• The advance parole document shows a validity period and may allow a single entry or multiple entries. Your return date must fall within the validity period.

The combined work permit and advance parole card

For people who file I-485, I-765 and I-131 together, USCIS may issue a work permit (Form I-766, Employment Authorization Document, EAD) with the notation “Serves as I-512 Advance Parole” on the card, meaning it also serves as an advance parole document, commonly called a combo card; or it may issue a work permit and a separate advance parole document (Form I-512L). Key points:

• Only a card bearing this notation can be used as advance parole. An ordinary work permit cannot be used to travel abroad and return;
• A work permit renewal receipt is not an advance parole renewal. After the old card expires, rely on the newly issued card or document;
• As of October 2026: starting in December 2025, USCIS shortened the maximum validity of work permits in certain categories, and work permits for applicants with a pending I-485 are now generally valid for at most 18 months. If you hold a combo card, plan your trip based on the expiration date actually printed on the card, not on past experience.

Parole is discretionary, and you still go through CBP on arrival

Advance parole is authorization given in advance by USCIS to “seek parole into the United States,” not a guarantee of entry. When you return to a U.S. port of entry, CBP inspects you and decides whether to parole you in. If CBP finds a ground of inadmissibility, it may refuse parole. The risk is noticeably higher for people with criminal records, past immigration violations, pending immigration court proceedings or a prior removal. For how to handle being taken to secondary inspection on arrival, see Secondary inspection at entry.

In addition, 2025 federal legislation added a statutory parole fee, which DHS has implemented since October 16, 2025. Under the exceptions listed in the DHS notice, properly filed I-485 applicants returning to the United States after a brief trip abroad are generally not charged this fee, but you must show that you qualify for the exception. We recommend carrying your I-485 receipt notice so CBP can verify it. Whether it applies in your case depends on current DHS, CBP and USCIS publications.

People with a history of unlawful presence: a major change in 2026

INA 212(a)(9)(B)(i) provides that a person who was unlawfully present in the United States for more than 180 days but less than one year and then departs is inadmissible for 3 years; a person who departs after one year or more of unlawful presence is inadmissible for 10 years. For more than a decade, the BIA in Matter of Arrabally and Yerrabelly, 25 I&N Dec. 771 (BIA 2012) held that leaving on advance parole was not a “departure” for this purpose and therefore did not trigger the bar.

As of October 2026: On August 13, 2026, in Matter of Delcarmen-Lara, 29 I&N Dec. 830 (BIA 2026), the BIA overruled Arrabally, holding that leaving the United States on advance parole is a “departure” within the meaning of 212(a)(9)(B)(i)(II), with the new rule applying prospectively. Practitioners generally understand that this meaning of “departure” applies to the 3-year bar as well. Practical effects:

• People who accumulated more than 180 days of unlawful presence in the United States after age 18 (for example, people who overstayed a visa and then applied to adjust status through a U.S. citizen spouse, or DACA recipients) who now depart on advance parole may be unable to adjust status after returning because of the 3-year / 10-year bar;
• Generally, time while an I-485 is pending is a period of authorized stay; the problem lies mainly in unlawful presence accumulated before filing the I-485;
• Trips that departed and returned before August 13, 2026 are generally handled under the old rule; for trips that departed before August 13 and returned afterward, the boundary is not yet clear;
• People with an unexecuted removal order who depart on advance parole may also be considered to have executed the removal order, triggering a separate reentry bar;
• Other bars such as 212(a)(9)(C) were never protected by Arrabally.

For a detailed analysis, see Matter of Arrabally explained. If any of the above applies to you, do not travel yet; decide only after an attorney calculates your unlawful presence and evaluates whether a waiver or an alternative is available.

Travel while I-751 or N-400 is pending

People with a pending I-751 or N-400 are already permanent residents, so travel generally does not require advance parole, and the application will not be treated as abandoned because of travel; what you need to watch is document validity and not missing USCIS notices. To check whether you can travel while various applications are pending, start with Can I travel while my application is pending?

I-751 / I-829 pending (conditional green card)

• After you timely file I-751 (or I-829), the I-797 receipt notice mailed by USCIS extends the validity of the conditional green card; the length of the extension is as stated on the receipt;
• When traveling, carry your passport, the original conditional green card and the original I-797 receipt notice;
• The receipt extension can be used only to return from an absence of less than one year; if you plan to be away one year or more, you need a re-entry permit (for re-entry permit validity for conditional green card holders, see above);
• You must return before the receipt’s extension period ends, and watch for biometrics and interview notices. If the extension expires while you are abroad, contact an attorney as soon as possible.

N-400 pending (naturalization)

• You must hold a valid green card when traveling; the N-400 receipt notice (I-797) issued by USCIS generally states that it extends the green card’s validity for 24 months from the expiration date on the card; if your green card has expired, carry it together with the receipt;
• Naturalization requires continuous residence from filing through the oath. A single absence of more than 6 months while the application is pending may be presumed to break continuous residence and lead to denial; a re-entry permit does not solve this problem;
• Most important is not to miss the interview and oath ceremony. Before a long trip abroad, arrange for someone to check mail sent to your U.S. address, and monitor your online account.

For naturalization requirements and time calculations, see Applying for naturalization on N-400.

Four documents compared

The SB-1 requirements are set by the U.S. Department of State: the applicant must prove they were a permanent resident when they departed, intended to return and did not abandon residence when they left, the trip was originally temporary, and the extended stay was due to reasons beyond their control. If the consular officer finds that residence was abandoned, you may only be able to apply again for an immigrant visa or a nonimmigrant visa. SB-1 is not a substitute for a re-entry permit; if you can get a re-entry permit in advance, do not count on fixing things afterward. If your green card or re-entry permit is lost or stolen abroad, the form to use is I-131A; see the explanation on the I-90 page.

Pre-departure checklist

• Confirm which document you need: green card and a long absence → re-entry permit; pending I-485 → advance parole (or confirm whether you qualify for the H/L/K/V exception); pending I-751 / N-400 → green card + I-797 receipt notice
• On the USCIS website, confirm the currently accepted I-131 edition, the filing address or online filing option, and the fee
• Re-entry permit: file inside the United States and allow time to wait for biometrics; depart only after biometrics are completed
• Re-entry permit: decide whether to have it mailed to a U.S. address or pick it up at an embassy or consulate abroad; if you choose an embassy or consulate, specify the city and confirm it offers the service
• Re-entry permit: confirm you do not hold another re-entry permit that is still valid; conditional green card holders should check how the permit’s validity relates to the I-751 filing date
• Advance parole: depart only once you have the document or combo card in hand; check that the card says “Serves as I-512 Advance Parole” and that your return date is within the validity period
• Advance parole: carry your I-485 receipt notice (to show you qualify for the parole fee exception), passport and the original advance parole document
• If you have overstayed or been out of status for more than 180 days, have a removal order, are in immigration court proceedings, or have an arrest or conviction record: see an attorney before departing
• Pending I-751 / N-400: carry the original green card and the original I-797 receipt notice, check the receipt’s extension period, and arrange for someone to receive mail at your U.S. address
• Green card holders with long absences: keep evidence of ties such as a U.S. residence, bank accounts and filing taxes as a U.S. resident
• Keep copies and electronic versions of all applications, receipts and approval notices, stored separately

Common mistakes

1. A green card holder applies for advance parole. If you pick the wrong type, the application will not solve the problem of a long absence.
2. Having family members file the re-entry permit while you are abroad. A re-entry permit requires you to be in the United States when filing and to complete biometrics in the United States.
3. Thinking a re-entry permit preserves your naturalization timeline. A re-entry permit only helps you keep the green card; it does not preserve the continuous residence required for naturalization.
4. Departing right after filing I-131. If an I-485 applicant departs before advance parole is approved, the I-485 and the advance parole application are generally both treated as abandoned.
5. Traveling on an ordinary work permit. Only a card annotated as valid for use as an I-512 is an advance parole document.
6. Thinking advance parole “erases” unlawful presence. After August 2026, for people with a history of unlawful presence, departing on advance parole may itself be the source of risk.
7. Wanting to extend an expired re-entry permit. A re-entry permit cannot be extended; you can only return to the United States and reapply.

How we can help

• Based on your status, travel history and itinerary, determine which document you need and the risks of the trip itself;
• Prepare and file I-131 (re-entry permit or advance parole), plan the timing of filing and biometrics, and request expedited biometrics in writing when needed;
• For people with overstays, removal orders, criminal records or pending immigration court proceedings, calculate unlawful presence before travel and evaluate waivers and alternatives;
• For people already abroad, with expired documents or considered to have abandoned residence, evaluate SB-1 and other next steps.
