Can I successfully navigate my visa plans upon arrival in Thailand with a 30-day visa exempt?

I did exactly that (using the banked funds method deposited on 17 Oct.) arriving in THA 30 Oct with a 30 day visa exempt stamp and a subsequent 30 day extension of stay. If you funded your account using a single bank to bank wire (vs. multiple Wise transfers), you will have an easier go. I would also advise using your first 30 days getting your permanent address nailed down and getting your TM30 buttoned up. Good luck.

Possible one of the keys in that schedule might be getting a long-term contract and TM30 for your accommodation if you don't have a place to live already.

It sounds really tight. Why not get the 60 day tourist visa that allows you one extension of 30 days ? This buys you more time.

The answer to that question is how fast can you get your shit together 😮 get the bank letter, get the documents you need and go apply for the initial 90 day Non-O visa?

MOST immigration offices require a minimum of 15 days left on your current stamp to apply for an in country Non-Immigrant type visa <- because it goes under review for 14 days and then you go back to get the Non-O and new 90 day stamp inked in. BUT some offices require a minimum of 21 days to do it 😕

Now you can get a 30 day extension on that 30 day visa exempt entry IF you need to so you can 'buy time' to get everything.

I'd say you SHOULD be able to pull it off from a 30 day visa exempt entry plus a 30 day extension if you need it.
