Yes — if you're flying to Cambodia on an e-visa or visa on arrival, you must show proof of onward travel. Cambodia's immigration authorities require all foreign visitors to present a confirmed onward or return ticket. Airlines enforce this before boarding.
Cambodia is a popular destination in Southeast Asia, particularly for travelers visiting the Angkor Wat temple complex in Siem Reap. While immigration at Cambodia's airports is often considered more relaxed than neighboring countries like Thailand and Vietnam, airlines are still strict about onward ticket verification before departure.
Cambodia's Onward Ticket Rule
Cambodia's immigration law requires that all foreign nationals entering the Kingdom must possess a return or onward ticket. This is a standard requirement for all visa types, including the popular e-visa (eVisa Cambodia) and Visa on Arrival (VOA).
The requirement is checked at two main points:
- Airline check-in — Airlines flying to Cambodia face fines for transporting passengers without proper documentation. Budget carriers like AirAsia, VietJet, and Cambodia Angkor Air are particularly strict about verifying onward tickets at check-in.
- Immigration at Phnom Penh (PNH) or Siem Reap (REP) — While Cambodia immigration is often less strict than its neighbors, officers still have the authority to request proof of onward travel, especially for travelers entering with one-way tickets.
Cambodia E-Visa Rules
Cambodia's e-visa (eVisa Cambodia) allows citizens of most countries to apply online for a 30-day, single entry tourist visa. Key rules:
- Cost: $36 + processing fee
- Processing time: 3 business days typically
- Valid for 90 days from issue date
- Onward ticket required — must be dated within your 30-day stay
- Enter through designated entry points (PNH, REP, and a few land borders)
Visa on Arrival
Cambodia offers Visa on Arrival to citizens of most countries:
- Tourist Visa (T): 30 days, $30
- Business Visa (E): 30 days, $35
- Both require a valid passport with 6+ months validity
- Passport photo required (bring one to save time)
- Onward ticket required — must be dated within 30 days
Land Border Crossings
Cambodia shares land borders with Thailand, Vietnam, and Laos. If you're entering Cambodia overland (e.g., from Thailand at Poipet), onward ticket checks are less common. However:
- The airline on your departing flight to Cambodia will still check your onward ticket before boarding
- Land border officials occasionally ask for proof of onward travel
- Having a verifiable onward ticket is still recommended for peace of mind
What Happens If You Don't Have an Onward Ticket?
While Cambodia is one of the more lenient countries in Southeast Asia:
- The airline may deny boarding at check-in if you cannot provide proof of onward travel
- If you arrive without proof, immigration may question your travel plans
- In rare cases, you may be denied entry and required to purchase a return ticket on the spot
- Overland entry without an onward ticket is lower risk but still technically required
