I used my home in the USA bank was fine showing 3 months worth of income. Is it true you only need to show the nessary income in your bank. Or 800,000 bt. In thai bank. Is the bank account still nessary in Thailand to get 1 year extension? My biggest hold up has been my rap sheet from FBI. They told me it will take 58 days. Then later found out I could have submitted it online. Which would have taken less than a week.
Be sure to apply for a criminal background. Check through the FBI fingerprint included. With a check for $18. That was my biggest holdup. Just Google FBI rap sheet.
There is a form on there website you will need to fill out. And get fingerprint at your local police station with a certified check for 18 dollars. This is the website
