Usually I will not spend over 6mo in Thailand, but when the time comes we'll have more info as it will be in around 6 months. I think a good idea is to have sponsorship as it is with what I applied for, statement from my mom's bank updated and also mine with a 500k transfer I guess.
That was my intention, but I read many places that it should be 6 months balance to make sure it is not a single loan. But now also many people say that with a single loan is enough...
