let me ask you a question, you think you are entitled because you have money so you can live anywhere you want? Your own country wouldn't let someone live there year round with only 4k pension. I worked in the US, employed over 100 US people and every year it was a pain for me to renew my visa. If you want to live in Asia then pat the price, buy an elite visa for 10 years, then once you are 50 you can get a retirement visa. Much easier than anyone trying to live in the USA.
If you have access to your bank back home just transfer money to a friend's thai bank account and have them withdrawal it and give to you, or if you have a credit card do a cash advance then pay it off right away via your online banking.
