I'm travelling in Southeast Asia and going to apply for tourist visa in Thai embassy in Malaysia or Cambodia. I'm going to travel by bus, train, or maybe bus/train + cross the border by foot. Visa application checklist says I need
A Copy of reservation/confirmation of return ticket (ticket in and out of Thailand)
I'm not sure if overland tickets will be good for this (esp. if it's tickets to/from the border). Does anyone have experience with bus or train tickets or no tickets at all? Maybe overland ticket to Thailand and plane ticket out of Thailand?
Note that I know it's possible to book a ticket for 24 hours without paying. But it means some amount of risk and also it's a lie (I'm not going to buy those tickets) which I'd like to avoid.
Extra note (if relevant): it's not a visa run, I've never been to Thailand before.
