Qatar air way dident let me bord the plane without a return ticket.
The reason was… if they don’t let me in to thailand . Qatar have to take me out. But since you already been accepted to enter thailand there should not be a problem..
But if it was me i shop around for ticket and prices.so if they start fucking around with you. You just open the phone and buy any ticket out.
You need to go to immigration one time, bring foto like passport
And tell them you need a Recife t certificate.
You need a letter from the Owner where you stay. Tell immigration officer you need a paper for open bank
Cost between 200-400 bath. Then go try open a bankaccount and transfer mony. Do al this as soon as you come Thailand. When have bankbook show you have mony then go to immigration and ask what they want from you to do an 1 year extensions.
I only have had good experience from immigration.
If you nice to them they are normaly very help full… why spend mony on agents
