Simple. Unless you have 800.000 Bath to put in a Thai bank account you can get a visa agent who is working with the bank and immigration. They will put that money for a few hours in your account while immigration gives you the stamp.. and you get the 12 months. When it expires you repeat the process. It’s the retirement visa and available for everyone above 55. You pay 18.000 to 20.000 Bath for this service. Each time. All visa agents in Thailand provide this service. 😉
I have seen mosquitoes suck blood out of the ”unbitten”. Many times. Some people simply get zero reaaction from the bites. They just don’t feel it. And they think they don’t get bitten. My niece is like that. She lives by a swamp in Northern Queensland and has no flyscreens in her windows. 😉
