Travel and maintaining your status
Whether you are going abroad to care for parents, accompanying a child at school, traveling for business or visiting family, the same question comes up: once you leave, can you get back in without trouble? A green card holder who stays away too long may be considered to have abandoned permanent resident status; leaving while an application is pending causes some applications to be treated as abandoned; visa holders returning to the U.S. need a valid visa, I-20, EVUS enrollment or ESTA; and at entry you may be sent to secondary inspection or even asked to let officers inspect your phone. This section, prepared by our managing attorney, David Wang, explains the rules status by status, how high the risks are, what to do before you leave, and how to respond within the law if you are stopped at entry.

My status → what to check before leaving
The table below summarizes the general rules; specific situations may have exceptions. If you have a history of long absences, visa refusals, unlawful presence, a removal order or a criminal record, be sure to consult an attorney before you leave.
| My status | What to check before leaving |
|---|---|
| Green card holder | Carry a valid green card and passport. If a single absence lasts more than 180 days, you may be treated as “seeking admission” on return; once you have been away one year, the green card can no longer be used as an entry document. If you plan to be away for about a year or longer, file Form I-131 for a re-entry permit in the United States before leaving and complete biometrics in the United States; a re-entry permit is generally valid for up to 2 years. For naturalization, a single absence of more than 6 months is presumed to break continuous residence. |
| Conditional green card (two-year card) | While the card is valid, the travel rules are the same as for a regular green card. If the card has expired but you filed I-751 or I-829 on time, travel with the expired green card and the I-797 receipt notice; the extension period is as stated on the receipt, and you must return within it. File I-751 within the 90 days before the card expires, and do not let travel cause you to miss the filing window, fingerprints or an interview. |
| I-485 pending | Leaving without advance parole usually causes the application to be treated as abandoned. There is an exception for people in valid H-1B / H-4 or L-1 / L-2 status who return in that status (the principal must return to work for the same employer). For anyone who was unlawfully present in the U.S. for more than 180 days, after the August 2026 BIA precedent decision, even leaving on advance parole may trigger the 3-year / 10-year bar; you must consult an attorney before leaving. |
| I-751 / N-400 pending | Travel is generally possible. I-751 pending: carry your green card and the I-797 receipt notice, and note the extension period on the receipt. N-400 pending: carry a valid green card; you must maintain continuous residence from filing until the oath, and do not miss biometrics, the interview or the oath ceremony. |
| H-1B / L-1 and other work visas | To return you generally need an unexpired visa of the matching category in your passport and a valid I-797 approval notice; we recommend carrying an employment verification letter from your employer and recent pay stubs. If your visa has expired, you must renew it at a U.S. embassy or consulate abroad: since September 2025, most applicants must interview and should generally apply in their country of nationality or residence, so allow extra time. |
| F-1 students | To return you need a valid passport, a valid F-1 visa and a valid I-20 with a travel signature from the designated school official (DSO). Most schools treat a travel signature as valid for 12 months, and generally 6 months during OPT; during OPT also carry your EAD card and proof of employment. If you will be outside the U.S. for more than 5 months, you may need a new I-20; ask your school’s international student office before leaving. |
| B1/B2 visitors with Chinese passports (EVUS) | Holders of passports of the People’s Republic of China with a 10-year B1/B2 visa must have a valid EVUS enrollment before each trip to the U.S.: an enrollment is valid for 2 years or until the passport or visa expires, whichever comes first; a new passport requires a new enrollment. Without a valid enrollment you cannot board. How long you may stay on each trip is determined by the I-94 issued at entry. |
| Taiwan passports (ESTA) | People who hold a Taiwan e-passport that includes a personal identification number and who have household registration in Taiwan may travel to the U.S. for tourism or short business trips under the Visa Waiver Program, and must obtain a valid ESTA authorization before departing. Each stay may not exceed 90 days, and you generally cannot extend your stay or change status in the U.S. People with visa refusals, overstays or travel to certain countries may not qualify for ESTA and must apply for a visa. |
Hong Kong SAR and Macao SAR passports are not covered by EVUS and are not in the Visa Waiver Program; travel to the U.S. generally requires a valid visa. Phones, computers and other electronic devices may be inspected by CBP at entry; for the rules, see Secondary inspection and phone searches at entry.
Recent changes (as of October 2026)
- Visa interviews: Since September 2, 2025, the U.S. Department of State has ended interview waiver eligibility for most nonimmigrant visa applicants (with exceptions such as certain B1/B2 renewals); since September 6, 2025, it has required nonimmigrant visa applicants to apply generally at a U.S. embassy or consulate in their country of nationality or residence. If your visa has expired and needs renewal, allow more time before you leave.
- Entry restriction proclamation: The entry restriction proclamation in effect since June 2025, and expanded on January 1, 2026, does not list mainland China, Hong Kong, Macao or Taiwan; the proclamation does not apply to green card holders. The list may be adjusted again, so verify it before you travel.
- ESTA: In December 2025, CBP published a proposal to require ESTA applicants to provide more information (including social media information). When you apply, follow the form and requirements on the official ESTA website at that time.
- Advance parole and unlawful presence: In August 2026, the Board of Immigration Appeals (BIA), in Matter of Delcarmen-Lara, overruled Matter of Arrabally: leaving on advance parole may also be considered a “departure,” triggering the 3-year / 10-year unlawful presence bar. Anyone with a history of unlawful presence must consult an attorney before leaving.
These policies have changed frequently in recent years; before you travel, check the latest announcements from CBP, USCIS and the U.S. Department of State.
Frequently asked questions
How long abroad is “too long” for a green card holder?
There is no “absolutely safe” number of days. Legally there are two important milestones: if a single absence lasts more than 180 days, you may be treated as seeking admission and reviewed on return; once you have been away one year, the green card can no longer be used as an entry document. But even with an absence of less than six months, if you mainly live abroad long term and have no residence, job or tax filings in the U.S., you may still be challenged as having abandoned permanent resident status. You can start with the green card travel risk assessment and then read the long absence guide.
I have been abroad for more than a year without a re-entry permit. Can I still use my green card?
The green card itself can no longer be used as an entry document. If the extended stay was due to reasons beyond your control (for example, serious illness), you may consider applying to a U.S. embassy or consulate for a returning resident visa (SB-1, Form DS-117); you must show that you intended a temporary departure when you left, that you always intended to return, and that the extended stay was beyond your control. Whether you qualify, and whether there are other options, requires an attorney’s assessment of the specific facts.
If I am sent to secondary inspection at entry, can I ask for an attorney to be present?
Under 8 CFR 292.5(b), a person applying for admission generally has no right to be accompanied by an attorney in primary or secondary inspection (except where the person has become the focus of a criminal investigation). You can answer questions truthfully and briefly, decline to sign documents you do not understand, write down the officer’s name and badge number, and contact an attorney as soon as possible afterward. If you are detained, you can ask to contact an attorney; CBP may say no, but making the request is itself significant for the record. See Secondary inspection and phone searches at entry.
The officer asked me to sign Form I-407 to give up my green card. Do I have to sign?
No. Form I-407 must be signed voluntarily. A green card holder can refuse to sign and ask for an immigration judge to decide whether permanent resident status has been abandoned; in that case CBP may issue a Notice to Appear, and the case goes to immigration court. It is best to consult an attorney before signing, and do not sign documents you do not understand under pressure.
What if I am asked to unlock my phone at entry?
CBP may inspect electronic devices at the border. CBP Directive 3340-049B, effective January 1, 2026, replaced the previous 049A and continues to distinguish basic searches (an officer looking through the device manually) from advanced searches (connecting external equipment to copy or analyze it); advanced searches have stricter thresholds and approvals. The consequences of refusing to unlock a device depend on your status: a U.S. citizen will not be denied entry for refusing, but the device may be detained; for a noncitizen visitor, refusal may affect whether you are admitted. Do not delete or hide evidence, which can lead to more serious consequences. See Secondary inspection and phone searches at entry.
I forgot to update my EVUS. Can I do it at the airport?
We do not recommend it. Travelers with Chinese passports and 10-year B visas who lack a valid EVUS enrollment cannot board, and the airline cannot issue a boarding pass; some enrollment results may take up to 72 hours. We recommend checking that your EVUS is valid before you book tickets, enrolling again after getting a new passport, and using only CBP’s official EVUS website.
