Philippine Airlines is the only carriers that required. But they where being overly stupid since I was returning on a multi entry one year extension. Had to argue with the supervisor regarding the fact that I live in Thailand
arrived as tourist and converted to non-o the 1st year. Now going into the third year so all sorted. Next renewal in a month.
I really wanted to go non-o for the added flexibility in selecting medical insurance outside of the Thai approved list. Applying from within the US it seemed difficult as the closest Thai embassy was in Los Angeles. Plus required police reports, medical reports, etc. etc.
If you already arrive with the non-o visa in theory you should be able to open a bank account and deposit the required funds and then submit the application for extension.
I was not able to get a bank account opened when I first arrived so I did hire an agent to get that handled.
Using an agent to get the bank account opened and process the immigration documentation correctly can be helpful first time around.
Beware! It is best to have your own funds ad required for the visa you are requesting. If the agent funds the account it is not legal and you will not meet the qualifications for renewal next year.
same here! Even though I had the money the agent still deposited the funds and immediately withdrew later the same day. I then deposited my funds into the account. But next years renewal the bank would not certify the funds stayed in the account for the post extension 3 month period.
