Long trips home happen. A parent falls ill, a project overseas runs long, a child is born. If you hold permanent residence somewhere, time away can put that status at risk, and every country sets its own clock. This guide is for green card holders, UK settled residents, Canadian permanent residents and UAE residence visa holders who want to know two things: which document gets them back, and where a flight reservation does or does not fit. We quote the official rule for each country and keep our own advice clearly separate.
Re-entry permits and returning residents: key facts
| Country | Time-away limit before trouble | Document that protects or restores status |
|---|---|---|
| United States | A green card's travel validity is one year; longer absences generally need a re-entry permit or a new immigrant visa.[2] | Re-entry permit, generally valid 2 years, applied for while in the US.[1] |
| United States (status lapsed abroad) | Abroad longer than one year or beyond the permit's validity.[2] | Returning Resident (SB-1) immigrant visa from a US embassy.[2] |
| United Kingdom | Indefinite leave to remain lapses after 2 continuous years away (5 for most EU Settlement Scheme settled status).[3] | Returning Resident visa, £726.[3] |
| Canada | Status survives an expired card, but you need a document to board.[4] | Valid PR card or a PR travel document (PRTD).[4] |
| UAE | Residence visa nullified after more than 180 continuous days abroad.[5] | Entry permit for residents abroad over six months, applied for from outside the UAE.[5] |
What is a US re-entry permit and who needs one?
A re-entry permit is a travel document issued by USCIS on Form I-131 to lawful permanent residents and conditional residents. It lets you apply for admission on your return without first getting a returning resident visa from a US embassy.[1]
The rules worth knowing, all from the current I-131 instructions:[1]
- Validity: generally 2 years from the date of issue. If you have spent more than 4 of the last 5 years outside the US since becoming a permanent resident, USCIS limits it to 1 year, with listed exceptions such as US government orders.
- Where you file: you must be physically in the US when you file and when you complete biometrics.
- Collection abroad: you can ask for the permit to be sent to a US embassy, consulate or USCIS office abroad, though not every post offers pick-up.
- What it protects: while it is valid, USCIS will not treat you as having abandoned residence based solely on the length of your absences.
- What it does not do: it does not exempt you from any other requirement of US immigration law.
- Citizenship clock: an absence of a year or more generally breaks continuous residence for naturalisation, whatever the permit says. Form N-470 exists for some people in that position.
In short, a re-entry permit protects your green card against the length of a trip. It does not protect your naturalisation timeline, and it cannot fix other problems.
What if you stayed abroad too long? The SB-1 returning resident visa
The State Department says a permanent or conditional resident who has stayed outside the US for longer than one year, or beyond the validity of a re-entry permit, will need a new immigrant visa to resume residence.[2] For those whose stay was beyond their control, the route is the Returning Resident (SB-1) visa.
To qualify you must show the consular officer that you were a permanent resident when you left, that you left intending to return and have not given up that intention, and that the protracted stay was caused by reasons beyond your control.[2] The State Department advises contacting the nearest embassy or consulate well ahead of travel, at least three months if possible.[2]
Example, purely to illustrate: say a green card holder from Hyderabad flew home for six weeks, then spent fourteen months caring for a parent after surgery. The green card's one-year travel validity has passed and there was no re-entry permit. That person is looking at an SB-1 application, with medical records and evidence of continuing US ties carrying most of the weight.
How do the UK, Canada and the UAE handle returning residents?
United Kingdom: indefinite leave and the Returning Resident visa
GOV.UK says you lose indefinite leave to remain after more than 2 continuous years outside the UK, Channel Islands and Isle of Man. For settled status under the EU Settlement Scheme the limit is 5 continuous years, or 4 for Swiss citizens and their family members.[3] Away for less than that, you still hold ILR and prove it on return through your eVisa, a share code or your original documents.[3] Beyond it, the Returning Resident visa costs £726 and asks you to show strong ties to the UK and explain why you lived abroad.[3]
Canada: PR card or PR travel document
Canada separates status from the travel document. IRCC says a permanent resident needs a valid PR card when travelling to Canada by plane, train, bus or boat and when transiting through a Canadian airport. If the card has expired or been lost, you apply for a PR travel document (PRTD); without one of the two you may not be able to board. An expired card does not, on its own, end your permanent residence.[4]
UAE: the 180-day rule and the return permit
The UAE government portal says an expatriate resident's visa is nullified automatically after more than 180 continuous days abroad. Residents in that position can apply from outside the country for a permit to enter, after 180 days away, giving a valid reason and paying AED 100 for every 30 days or part of 30 days spent outside. Once approved, you must enter within 30 days. Dubai residents use a different procedure, and golden visa and green residency holders do not need the service while their residency is valid.[5]
That 30-day window is the one place in this guide where flight timing is written into the rule. Our UAE visa guide covers entry visas more generally.
Side-by-side: the main returning resident documents
| Document | Apply from | Validity or deadline | Flight evidence officially required? |
|---|---|---|---|
| US re-entry permit | Inside the US, before leaving[1] | Usually 2 years; 1 year in some cases[1] | Not in the I-131 evidence list we read[1] |
| US SB-1 returning resident visa | US embassy or consulate abroad[2] | Contact the post at least 3 months ahead if possible[2] | Not stated on the summary we could read |
| US refugee travel document | Inside the US, before leaving[1] | 1 year, cannot be extended[1] | No |
| UK Returning Resident visa | Outside the UK[3] | Needed after 2 years away (5 for most EUSS)[3] | Not listed on the GOV.UK summary |
| Canada PRTD | Outside Canada[4] | Needed to board if no valid PR card[4] | Not stated on the page we read |
| UAE permit for residents abroad over six months | Outside the UAE[5] | Enter within 30 days of approval[5] | Not stated; the deadline drives your booking |
Refugees and asylees in the US use a different travel document; it is covered in our refugee travel document guide.
Where does a flight reservation actually help?
Honestly, for the permits themselves, less than many websites suggest. None of the official pages above lists a flight booking as required evidence. So treat what follows as our practical advice, not an official rule.
1. Showing a planned return date. SB-1 and UK Returning Resident applications turn on your intention to return and your ties. A held reservation for a realistic return date can sit alongside the strong evidence, such as job offers, leases and family records. It is a supporting detail, never the main proof.
2. Visas for other countries while you are abroad. If you hold a re-entry permit and travel onward, say to Europe during a long stay in India, the ordinary rules for that destination apply. Schengen checklists often want a reservation; see our Schengen guide.
3. Planning around a hard deadline. The UAE's 30-day entry window, or a re-entry permit that expires on a fixed date, gives you a target. Holding a seat for a date inside the window lets you plan without paying for a ticket before the permit is approved.
4. Coordinating family members. When a spouse or children hold different documents, for example one on a re-entry permit and another needing an SB-1, a single planned return date gives everyone the same target. Each person's papers are decided separately, so check that every family member's document will be valid on that date before anyone buys a ticket. Our guide to family and group bookings covers the naming side.
What we would not do: buy a non-refundable ticket before an SB-1 or Returning Resident decision. Consular timelines are not in your control, and the State Department's general advice for visa applicants is not to buy tickets until you have the visa.[6]
What does the airline check when you fly back?
Airlines check that you hold a document allowing you to travel to your destination. For returning residents, that document is the residence evidence, not the ticket. Canada says so directly: without a valid PR card or PRTD you may not be able to board.[4] For the US, the State Department's guidance makes the green card's one-year travel validity and the re-entry permit's two years the key windows.[2] For the UK, you prove status with your eVisa, share code or original documents.[3]
Two practical habits help at the desk. Carry the physical permit or card, not a photo of it. And book the real ticket in the name exactly as it appears on the passport you will travel on; our page on name format explains the common traps.
Planning a long absence: step by step
- Estimate how long you will be away, then add a margin for delays.
- Compare that with your country's limit: one year on a US green card, two years for UK ILR, 180 days for most UAE residence visas.
- If you are in the US and may stay away a year or more, file Form I-131 for a re-entry permit and attend biometrics before you leave.
- Ask for the permit to be sent abroad if you will leave before it is issued, and check that your chosen post offers pick-up.
- Keep evidence of ties: lease or property records, tax filings, employer letters, bank accounts.
- Plan the return flight inside the validity window. Hold a seat while documents are pending if it helps you plan, then buy once the date is certain.
- Check the PNR on the airline's site if you are using a held booking anywhere in an application; our verification guide shows how.
A note on timing. Our reservations remain active for up to 2 weeks; each airline sets its own precise expiry within that. Because permit decisions can drag on, order the reservation once you know when your appointment or decision is due, not months before.
Price for a planned return reservation
Pricing does not change with your residence category. It is a flat amount per traveller, for a single direction or a round trip, with multi-city itineraries counted in pairs of legs.
The booking is made on a real flight with a live PNR and sent by email, usually within about 10 minutes. It is held rather than paid for, so it cannot be used to travel. Razorpay processes payment by UPI, card or netbanking, and order tracking shows progress. You can also read about all prices, visa reservations in general, country requirements, onward-ticket checks and hotel reservations, or start from the home page.

Important: immigration officers and consular staff decide your status. A reservation shows a plan; it cannot restore residence or replace any document listed above.
Re-entry permits and returning residents: frequently asked questions
Can I apply for a US re-entry permit from abroad?
No. The I-131 instructions say you must be physically present in the US when you file and when you complete biometrics. You can then leave and ask for the permit to be sent to a US embassy, consulate or USCIS office abroad for collection, where that post offers it.
How long is a US re-entry permit valid?
Generally 2 years from issue. If you have spent more than 4 of the last 5 years outside the US since becoming a permanent resident, USCIS usually limits it to 1 year, with exceptions such as travel on US government orders or work for certain international organisations.
Does a re-entry permit protect my path to US citizenship?
Not by itself. The I-131 instructions warn that an absence of a year or more generally breaks continuous residence for naturalisation. Some people can file Form N-470 to preserve residence for that purpose. The re-entry permit protects your green card, not your citizenship timeline.
I have been out of the US for 14 months without a permit. What now?
The State Department says you will generally need a new immigrant visa, usually the SB-1 returning resident visa if your extended stay was beyond your control. Contact the nearest US embassy early, ideally three months before you hope to travel, and gather evidence of your ties.
Is a flight reservation part of the re-entry permit or SB-1 paperwork?
We found no official requirement for one on the pages we checked. A held reservation can help you plan and can show an intended return date, but the decision rests on your status, intention and evidence of ties. A paid fare can wait until the consulate has answered.
My Canadian PR card expired while I was in India. Can I still fly back?
Your status continues, but you may not be able to board without a document. IRCC says you need a valid PR card or a PR travel document to travel to Canada by air. Apply for a PRTD from abroad before you book a firm travel date.
How quickly must I fly back after a UAE return permit is approved?
Within 30 days of approval, according to the UAE government portal. The permit is for residents whose visas lapsed after more than 180 days away, and Dubai residents follow a separate procedure. Golden visa and green residency holders do not need it while their residency stays valid.
