Which school did you choose ? Some schools are very familiar with DTV requirements so they provides full documents. Some are not. If u want an example u can PM me I will send u the list
Entry rejection and deportation are 2 different situations:
- entry rejection : when you arrive , officer looks at your history and suspect that you don’t come to Thailand for pure tourist purpose ( many times visa run for example). They will stamp a rejected stamp on your passport and send you back to where you came from. But you are not blacklisted. If you wait for a while then you can come back. If you are in this situation u still can apply for all other types of visa just need a very solid documents
Also You can contact me I can guarantee smooth entry with a fee of 2500 THB.
- deportation: when you do something illegal and get caught by the police ( illegal work , drugs …. ) then you are deported and also blacklisted. To erase blacklist it’s very expensive and difficult these days.
For air ticket I have one solution when you need a return ticket to check in but you are not sure about the return date. I can issue one way ticket to go and the day of departure I will give you the return ticket to check in ( once you get through immigration on arrival we will cancel this return ticket. As an agent we can cancel ticket free of charge the same day) then you don’t have to pay change / refund fee
