Which Countries Require Proof of Onward Travel? (Country List)

Fly one-way, and the check-in agent or the border officer may ask how you plan to leave. Whether a ticket out is required depends on the country, your passport and how its rules are worded. The tables below sort 43 countries and the Schengen area for a US passport (the US row covers other passports) into “required”, “officers may ask” and “not listed”, each with its source, its wording and the stay you get, last checked on 23 Oct 2026.

Which countries require proof of onward travel

Proof of onward travel is a ticket or booking out of the country dated inside the stay you are given, and the wording of each rule decides which kinds count. Each of the 44 entries below falls into one of 3 groups for a US passport (the US row covers other passports):

• Required: 15 entries. A government rule says you must or should have a ticket out in Thailand, Indonesia (visa on arrival), Taiwan, Singapore, India (e-Visa), Costa Rica, Panama, South Africa and the US Visa Waiver Program. Airline requirement data says you “must have” one for the Philippines, Malaysia, Colombia, Belize, the Dominican Republic and New Zealand.
• Officers may ask: 23 entries. Airline data says a passenger without one “could be refused entry”, or a rule says an officer “may request” one.
• Not listed: 6 entries. Neither the airline data nor a government page checked here names an onward ticket for the UK, Turkey, Australia, Ecuador, Uruguay or El Salvador. That is not a promise that nobody asks.

Airline rows come from the check-in requirement data of a large international airline, read for a US passport holder living in the US. IATA says its Timatic service checks the documents of over 700 million passengers a year, so the first person to ask about your ticket out is often the check-in agent.

Onward ticket rules in Asia and the Middle East

Asia holds 5 of the 9 written onward ticket rules on this list, and 2 of the 6 airline “must have” rows.

Country	Onward ticket	What the source says	Stay, US passport
Thailand	Required	Thai embassy: confirmed air, train, bus or boat tickets out within 30 days of arrival	30 days visa-exempt since 15 Sep 2026
Indonesia	Required	Immigration office: a return or onward ticket, for the visa on arrival	30 days on a visa on arrival, extendable once to 60 in total
Taiwan	Required	Consular bureau: a confirmed return ticket, or a ticket and next-country visa, and a confirmed seat	Up to 90 days from the day after arrival, not extendable
Singapore	Required	ICA: short-term travelers “should have” cash and proof of onward travel	90 days
India	Required	e-Visa site: “should have” a return or onward ticket and enough money	e-Visa needed
Philippines	Required	Airline data: tourists and business visitors “must have” a return or onward ticket	30 days visa-free
Malaysia	Required	Airline data: “must have” a return or onward ticket	90 days, arrival day included
Vietnam	Officers may ask	Airline data: “could be refused entry” without a sticker visa	e-visa needed; 30 days visa-free on Phu Quoc
Cambodia	Officers may ask	Airline data: “could be refused entry”; the visa on arrival also lists a hotel booking and funds	Visa on arrival, up to 30 days
Japan	Officers may ask	Airline data: “could be refused entry”	90 days from the day after arrival
South Korea	Officers may ask	Airline data: “could be refused entry”	90 days
Sri Lanka	Officers may ask	Airline data: “could be refused entry”	eTA needed before you fly

Georgia	Officers may ask	Airline data: “could be refused entry”	Up to 1 year
Turkey	Not listed	Airline data: no onward ticket section	90 days in 180

Thailand: a ticket out within 30 days of arrival

Since 15 Sep 2026, a US passport gets 30 days visa-exempt in Thailand, and the exemption carries a written onward rule.

On a Thailand visa run, each return is a new visa-exempt entry, so the ticket out has to fall within 30 days of the new arrival date, not the first one. Because buses and trains are named, a bus ticket to Malaysia or Cambodia meets the words of the rule.

Philippines: tourists need a ticket out at check-in

Airline requirement data says tourists and business visitors on a US passport “must have” a return or onward ticket, with exceptions for spouses and children of Filipino citizens and for Balikbayans. The eTravel QR code, obtained at most 3 days before departure, registers your arrival and is not proof of onward travel.

Indonesia and Taiwan: the ticket is a condition of entry

Where the entry is a visa on arrival, the ticket can be a condition of the visa itself: Indonesia’s immigration office lists a return ticket or an onward ticket to another country for its 30-day visa on arrival. Taiwan’s visa-exempt entry rules ask for a confirmed return ticket, or a ticket plus a visa for the next country, and a confirmed seat on the departure flight.

Onward ticket rules in Europe

Europe is mostly an “officers may ask” region for a US passport. The Schengen Borders Code lists a return or round-trip ticket among the documents a border guard may request, in a list of examples that is not exhaustive. Airline data for France, Spain, Portugal, Greece and Croatia says “could be refused entry”.

The UK has no onward ticket section in airline data for a US passport, and visitors can usually stay up to 6 months.

Country	Onward ticket	What the source says	Stay, US passport
Schengen area	Officers may ask	Schengen Borders Code: a return or round-trip ticket is a document a guard “may request”	90 days in any 180
United Kingdom	Not listed	Airline data: no onward ticket section	Up to 6 months
Ireland	Officers may ask	Airline data: “could be refused entry”	No visa needed
Albania	Officers may ask	Airline data: “could be refused entry”	Up to 1 year
Montenegro	Officers may ask	Airline data: “could be refused entry”	90 days
Serbia	Officers may ask	Airline data: “could be refused entry”	90 days in 180

Onward ticket rules in Latin America and the Caribbean

In Latin America and the Caribbean, Costa Rica and Panama put an onward ticket in writing, and airline data says “must have” for Belize, Colombia and the Dominican Republic.

Country	Onward ticket	What the source says	Stay, US passport
Mexico	Officers may ask	Airline data: “could be refused entry”; UK advice: you “may need to” show one	Up to 180 days
Belize	Required	Airline data: “must have” a return or onward ticket if born outside Belize	Up to 180 days
Guatemala	Officers may ask	Airline data: “could be refused entry”	90 days

Uruguay	Not listed	Airline data: no onward ticket section	90 days
Brazil	Officers may ask	Airline data: “could be refused entry”	e-visa needed
Dominican Republic	Required	Airline data: “must have”, unless the passport shows birth there	60 days

Costa Rica: a bus ticket counts by law

Costa Rica asks non-residents for a ticket out if they arrive one-way, hold a return ticket dated more than 90 days after arrival, or fly in and out of different countries.

A pre-purchased bus ticket to Panama or Nicaragua meets those words, as long as its date falls inside the stay the officer gives you.

Panama and Colombia

Panama’s National Migration Service asks tourists for a passport valid for at least 3 months, proof of at least B/.500 and a verified booking to leave the country within the permitted period. The US State Department calls the return ticket rule “strictly enforced”, and for travelers leaving by land, airline data asks for a ticket that proves you leave Panama.

Colombia’s row rests on airline data, and the State Department adds that you may be denied entry without a return ticket.

Invented for illustration. Jo holds a US passport and flies one-way from Miami to San José on Monday 9 Nov 2026.

• Check-in for San José, 9 Nov. Arriving one-way is one of the cases where Costa Rica asks for a ticket out. Jo shows a pre-purchased bus ticket from San José to Panama City for 30 Nov, day 22 of the stay, and carries a bank statement for the funds check.
• Panama land border, 30 Nov. Panama asks for a booking out within the permitted stay and at least B/.500. Jo shows a flight from Panama City to Bogotá on 14 Dec, day 15 in Panama, and the same statement.
• Check-in for Bogotá, 14 Dec. Airline data says US passports “must have” a ticket out of Colombia. Jo shows a refundable fare from Bogotá to Miami on 1 Mar 2027: counting 14 Dec as day 1, that is day 78 of a 90-day stay.
• Result. 3 entries, 3 different rules, and each one met by a ticket out dated inside the stay it had to fit.

Onward ticket rules in North America, Oceania and Africa

The US rule applies to visitors on other passports. Under the Visa Waiver Program, travelers arriving by air or sea must hold a round-trip ticket valid for at least 1 year that does not end in Canada, Mexico or an adjacent island unless they live there. Land arrivals show evidence of funds and a home abroad instead.

South Africa’s Department of Home Affairs lists “a return or onward ticket” among what visitors need to enter, alongside funds and a valid passport.

Country	Onward ticket	What the source says	Stay
United States (Visa Waiver, non-US passports)	Required	Federal regulation: a round-trip ticket valid for at least 1 year	Up to 90 days
Canada	Officers may ask	Airline data: “could be refused entry”	Up to 6 months
New Zealand	Required	Airline data: NZeTA holders “must have” a return or onward ticket	Up to 3 months with an NZeTA
Australia	Not listed	Airline data: no onward ticket section	ETA needed before you fly
South Africa	Required	Home Affairs: “a return or onward ticket”, plus funds	Not checked here
Morocco	Officers may ask	Airline data: “could be refused entry”	90 days

How to check a country that is not on this list

The same 2 sources work for any border: the government’s own wording and the airline’s check-in data, read side by side.

How to check the onward ticket rule for any country

1. Find your stay on the country’s own immigration or embassy page, and note whether day 1 is the arrival day.
2. Search that page for “return ticket”, “onward ticket” and “onward travel”, and note whether it says must, should or may.
3. Enter your nationality, residence and destination in your airline’s passport and visa tool, and read its return or onward ticket section.
4. Sort the country as required, officers may ask or not listed, using the strongest wording from either source.
5. Match the proof to the words, such as a bus ticket only where the rule names buses.
6. Recheck both in the week before you fly, because stays change: Thailand’s 30-day stay for US passports dates from 15 Sep 2026.

What happens if you don’t have proof of onward travel

At check-in, an agent who sees “must have” or “could be refused entry” for your passport can decline to board you until you show a ticket out, and the fix at the desk is buying one at that day’s fare. At the border, the officer decides whether you enter.

Airlines check before you board because they carry the cost of a refusal. EU law makes the airline take a refused passenger back and requires fines with a maximum of at least €5,000 or a minimum of at least €3,000 per passenger, or a lump-sum maximum of at least €500,000 per infringement. The US charges airlines $7,093 per passenger brought in without required documents.

How to show proof of onward travel without a fixed exit date

Long stays rarely start with a fixed exit date, and there are 3 common ways to hold a ticket out before you have chosen one.

• A refundable fare. A paid, ticketed exit that you cancel later under the fare rules. The cost is cash tied up until the refund arrives.
• The US 24-hour rule. Covered airlines must hold a fare at the quoted price without payment, or let you cancel without penalty, for at least 24 hours if you book one week or more before departure. It covers US airlines, and foreign airlines only on flights to and from the US, so a flight between 2 foreign cities on a foreign airline is not covered.
• An onward ticket reservation. A held flight booking in your name with a booking reference, sold by onward ticket services whose prices, hold lengths and change terms differ.

If you would rather have a service make one, Dummy-Flights.com is one option: as of October 2026, $15 buys a one-way reservation, or $19 a round trip, for a flight you pick from a live search before paying, with a booking reference you can look up on the airline’s site, delivered as a PDF by email. There are no changes after booking and no refund once booked because plans changed. The airline decides how long the reservation stays live, and the confirmation shows the exact expiry time.
