At what stage of obtaining a marriage visa can I apply for a Thai driver's license?

@Rick ********

It’s one or the other, but only one for the first year as you don’t have time to prove the other.

So if you apply for a 90 days Non O based on retirement at the immigration in Thailand you’ll need to prove 800K baht in your account at date when you apply. If you apply for a 90 days Non O through the Thai embassy where you stay before you’ll leave for Thailand you’re able to prove income by showing prove of three months bankstatments with income equal to min 65K baht a month.

For the first year extension of stay after 90 days you’ll need to prove 800K baht in your account two months prior to your application and three months after the extension is issued and it can not drop below 400K baht. For your second year you’ll be able to prove twelve months consecutive transfers of min 65K baht and you can change to the income method.
