Discovered something enlightening today at Jomtien immigration. I was helping a friend apply for a Non-O visa. He deposited 800k in his thai bank account on March 17th, prior to his arrival on May 3. The Non-O woman told him to come back on May 17th because the money had not yet aged two months.
I was surprised to learn that the two month aging rule is applied to initial 90 day Non-O applications in Thailand. This means it is impossible to show up on a 30 day visa exempt, open a bank account, transfer money, and apply for a non-O all within a 30 day visa exempt stay. A 30 day extension wouldn't help either, because you have to apply at least two weeks before your admitted-until date (according to the woman in jomtien). Seems you have to travel to another country to wait it out, or arrive on a tourist visa and do a border bounce when it expires.
I'm curious if other people have run into this snag, or if this is particular only to jomtien. My friend was advised on other forums that the 2 month aging only applies to visa extensions, not the initial 90 day non-O.
O-A is not an option for my friend.
