You also have the option of using the Income Method and not use the Cash in the Bank method. You just have to affirm using an Affidavit Document from your Embassy in Bkk that you have income from any source outside Thailand equal to or greater than the equivalent of Baht each month. Americans need only to swear that they have this income and sign the Affidavit form.

Correct, but I felt the OP did not know about how the O-A visa actually works - and I was correct - and another fellow picked up on a useful aspect of the discussion. The correct info was given directly related to the actual question - at least two times - one by me. From his remarks the OP was quite pleased with all that he learned.

Yes, David and this is not the subject of O-A visa discussion

The original subject pertained to the Second Year of an O-A visa (having nothing to do with an Extension of Stay)

David, not sure but you may be crossing the two Visas / Extensions... An Extension of Stay done each year on an O Visa is not the same as much of this discussion relating to an O-A visa. Extensions of Stay done for one year always has the option of buying Reentry Permits should you want to Exit and Return to Thailand.

In the Second Year the O-A visa no longer has the Multi Entry aspect. In the second year you report every 90 days at Immigration and if you should leave Thailand you must pre-purchase a Reentry Permit before leaving Thailand

And the direct answer to your question - with a one year non Imm O-A visa no onward or return travel ticket will be needed.

With the O-A, visa in the first year you can Exit Thailand - visit other countries and come back to Thailand and not have to buy any Reentry Permits.

Greg - that is a great choice. The 0-A Visa is a Multi Entry Visa that says One Year but is actually a Two Year Visa. During the first year most O-A visa holders do the 90 day reports at the local Immigration. But as you come very near the First Year Expiry date you can Exit and immediately reenter Thailand and get another full year added.

Or are you going to apply for a 90 day Non Immigrant O Visa in Thailand or neighbor country and then apply for a One Year Extension of Stay based on that visa?
