How can I prove onward travel when applying for an SETV visa in Cambodia?

Just book an Air Asia flight to anywhere to fly on about day 57 of the 60.

Probably cost no more than 800THB

There are several companies that will sell you a "Ticket" like Flyonward but I heard several people having problems getting their confirmation within the last two weeks and they do not reply to any mails. The Facebook Site is down too. I suppose, people who wanted to scam immigration law, got scammed themselves ;-)

Now contrary to common believe those websites do not sell any tickets, they just sell you a PNR

A PNR is a database record on the airline's computer that holds the information about you and your flights. But crucially it is a separate system to ticketing, which are financial documents.

Many of those on-line companies are generating a Personal Name Register not a ticketed booking, which may fall foul of a very strict interpretation of the rules as the sole purpose is, to avoid compliance to immigration law.

There are other websites where you can print your own tickets, fake tickets. Should you get caught with one of them, you might even be prosecuted for trying to enter a country with a fake document.

The only legal way is to have a valid onward ticket, PNR is not.

You could always buy a 1 year open return, then keep changing dates and finally, use it or refund it. Why scam the system and in the end pay more, if you can use the system and get something for it ;-)

you should be ok..without onward proof of a flight out..they may ask you to show bhat to prove you can look after yourself for the 30 day visa..

When you're getting a tourist visa at a thai consulate for proof of onward travel within 60 days some people use a bus ticket and it's accepted.

There are a few internet sites that rent you a ticket for onward travel and to my knowledge they're accepted for the proof.

For that second SETV you're thinking of getting in Malaysia you're gonna need to show proof of onward travel at the thai consulate in Penang or KL too.
