The trip comes up at the worst moment: a parent is ill, there’s a wedding, or work sends you abroad, and you have an immigration application stuck in processing. The one-line answer is that leaving can cancel your application or your right to come back, and the rules differ in ways that catch people out. Our interim visa guide explains what status covers you while you wait. This guide covers the travel side: what happens at the border, the exceptions, and what to check before you book.
Disclaimer: This is general information, not legal advice. Immigration rules depend on your exact status and history. Confirm your situation with the relevant immigration authority or a licensed immigration lawyer before you travel. Some of these mistakes can’t be undone.
United States: Advance Parole, or your I-485 may be abandoned
USCIS’s current Form I-485 instructions (edition 09/18/26) are blunt. If you travel anywhere outside the US while your adjustment application is pending, “including brief visits to Canada or Mexico,” USCIS treats it as abandoned unless one of these applies:
- You got Advance Parole first. File Form I-131, get the document before you leave, then return through a port of entry and be inspected and admitted or paroled.
- You hold and are maintaining H-1B/H-4, L, V, or K-3/K-4 status, and you come back with a valid visa in that category (if one is required). USCIS’s H-1B FAQ adds that an H-1B worker must remain eligible for H-1B status and resume work for the same H-1B employer.
- You are a TPS beneficiary travelling with authorization under INA section 244(f)(3).
Two warnings from USCIS’s travel documents page matter even if you have Advance Parole. First, “admission or parole into the United States is not guaranteed.” Second, if you’ve built up unlawful presence or have a removal order, you may be found inadmissible when you return, even with a travel document. If you are one of these applicants, speak to a lawyer before you leave. Advance Parole won’t protect you. (If you’re still deciding how to file, see adjustment of status vs. consular processing. H-1B holders should also read our H-1B to green card guide.)
United Kingdom: leaving the CTA withdraws your application
The UK has two separate rules, and they work differently:
- Your application. Home Office caseworker guidance (Validation, variation and withdrawal of applications, version 11.0, published 5 August 2026) says that if you applied for permission to stay and travel outside the Common Travel Area before a decision, your application must be treated as withdrawn on the date you left. The CTA is the UK, the Republic of Ireland, the Channel Islands, and the Isle of Man. This applies even if you never told UKVI. Caseworkers can find the trip from Exit Check data. If biometrics or online documents were already submitted, the fee isn’t refunded.
- Your 3C leave. If your old visa expired while you waited, you’re probably on Section 3C leave. The Home Office’s 3C guidance says “section 3C leave will end if the person leaves the UK.” It says leaving the UK, not leaving the CTA.
In practice, a trip abroad usually costs you the application, the fee, and possibly your lawful basis to return, all at the same time. Don’t treat even an Irish trip as safe without advice. This is especially costly if you’re applying on the way to Indefinite Leave to Remain.
Canada: possible, but your temporary status decides re-entry
Canada doesn’t automatically cancel a pending PR application when you travel. The risk is getting back in and what status you return on:
- You need the right entry document. IRCC says a work permit doesn’t let you travel or re-enter by itself. You need a temporary resident visa (TRV) or an eTA, depending on your citizenship. IRCC also warns that having one “doesn’t guarantee that you can re-enter Canada.”
- Maintained status doesn’t come back with you. If you applied to extend your work permit and leave before it’s approved, IRCC says you can re-enter only as a visitor and cannot work until it’s approved. This often happens to people waiting on a Bridging Open Work Permit.
- The final step needs you in Canada. IRCC’s PR confirmation portal requires you to be physically in Canada to confirm PR status online. If you plan to travel before you get your e-COPR, IRCC says to contact them at the email address on your invitation. If you leave after becoming a PR but before your card arrives, you’ll need a Permanent Resident Travel Document to fly back.
Australia: only a Bridging Visa B lets you travel
Australia has the strictest rule of all because it depends on a single document. Home Affairs says only a Bridging Visa B (BVB) lets you leave and re-enter while a substantive visa application is processed. A BVA does not let you return if you leave, and leaving on any other bridging visa generally ends it.
To get a BVB (form 1006 or ImmiAccount), you must hold a BVA or BVB, show substantial reasons for travelling, and your return must not be against the public interest. It is granted with a set travel period based on your reason for travel and when a decision is expected. Plan to return within those dates. Get the BVB granted before you fly. Just lodging the application isn’t enough.
Before you book: a 60-second check
- Find out exactly what status you hold today (EAD/AP card, 3C leave, maintained status, BVA).
- Look for written permission to travel and re-enter, with dates that cover your whole trip.
- If you’ve ever overstayed, had a refusal, or had a removal order, speak to a lawyer first.
- Don’t rely on “I’ll explain at the border.” Officers decide on the spot.

FAQ
Does a short trip to Canada or Mexico count as leaving the US while my I-485 is pending? Yes. USCIS’s Form I-485 instructions say travel anywhere outside the United States, including brief visits to Canada or Mexico, causes the application to be treated as abandoned unless you have Advance Parole or fall into a listed exception such as maintaining H-1B, L, V, or K-3/K-4 status and returning with a valid visa.
Can I visit Ireland while my UK application is pending? Ireland is inside the Common Travel Area, so the Home Office’s rule that an application is treated as withdrawn on leaving the CTA is not triggered. But the Home Office’s separate 3C guidance says 3C leave ends if you leave the UK, so if you are relying on 3C leave, get advice before any trip, even to Ireland.
I already left Australia on a Bridging Visa A. What now? Home Affairs says a BVA does not let you return once you leave; departing generally ends that bridging visa. You would need a visa to re-enter. Contact the Department of Home Affairs or a registered migration agent about your options.
Is my Canadian PR application cancelled if I travel? Leaving Canada does not by itself cancel a PR application, but coming back depends on your temporary status and travel documents. If a work permit extension is still pending, IRCC says you can only re-enter as a visitor and cannot work until it is approved, and you need a TRV or eTA if your citizenship requires one.
Does having the right travel document guarantee I’ll be let back in? No. USCIS states admission is not guaranteed even with the appropriate documents, and IRCC says an eTA or visa does not guarantee re-entry. Border officers decide at the port of entry.
