If you have year long visa for retirement, marriage and work, you can apply but they ask you to deposit money and they lock that amount and keep it as a gurantee and money you deposit is your credit card limit.
regarding the 3rd option, let s say you went with that option and got a non o. what about the following year if you didnt earn 40 000 or dont have a work permit? Do you need to show 400 000 thb?
they always or mostly check bc they are required to do so by Thai authorities. If an airline get someone to Thailand without a return ticket, they fine that airline.
haha in my profile?? :) anyway are you a sneaky pervert checking people s accounts and following their lives and asses around? Sounds weird my friend :)
