***he is a U.S. citizen (by his profile) so there won’t be an embassy affidavit of income. He will definitely need to use the 800,000 THB deposit method in the first year
***he needs to open a Thai bank account immediately after entering
***there is NO NEED for proof of foreign source for the minimum of 800,000 THB in his Thai bank account when applying for the 1-year EOS
*** for the application to the “1-year extension of stay based on retirement”, he needs proof of a 2-months seasoning, though
