hi and thanks for the comprehensive answer. If already married in Thailand is the original marriage certificate and registration document ok or do you need an additional document? Thanks.
spot on, i opened the bank account 2 weeks ago and dtac gave me the same document you describe showing full name and new number. Just had to asked dtac for it when I got my sim a few days before.
I recently did the non O 90 day bias through Thai consulate Sydney. It's all done online easy to do, you need to show proof of funds of 800k baht in your Australian bank in Aud dollar equivalent of $40k. Visa approved and emailed to me 10 days later. Cost about $120 fee to Consulate paid onIine when applying. Website keeps you posted on status of processing.
