within 60 days if asked

You will need the Thai bank account to get your Non-O in country so get your Non-O before travelling if possible

It's your airline that might require to see onward travel within 60 days, ask them

@Jeff ******

it has everything to do with the original question as the ETA will definitely not commence in May but the TM6 might

Have you considered the Non-OX which is popular with Aussie retirees?

@Bob *********

Canadian Embassy is stopping the income affidavit at the end of the month so it's a last chance for anyone that wants one (it's valid for 6 months)

Do you already have a Thai bank account for the 800k international transfer?

@Ollie ******

So you will not be coming back Visa Exempt

@Jeff ******

It might matter to the OP as the ETA will be for those entering on a Visa Exempt stamp whereas the online TM6 will apply to everyone without a Thai passport regardless of visa status

Get your Non-O marriage Visa and arrive in Thailand with a 90 day entry stamp and file a TM30 at Immigration (or online). Get a residence certificate from Immigration and use it to open a Thai bank account in your name and do an international transfer of at least 400k within the first couple of weeks. Season the money for 2 months, get the necessary documents from your bank then apply for your first Extension of Stay at Immigration (1900B for 12 months). If you stay 90 days or more on this Extension start doing 90 day reports. You need a re-entry permit (1000B from Immigration or at the airport while departing) to keep your 12 month stamp for your return to Thailand next time.
