What are the best visa options for staying in Thailand while waiting for my wife's CR1 visa approval?

If you don't have at least 65.000 Baht income per month, don't come

Why didn't you go with a K1 visa, my fiance is thai and I believe that's the way we are going,

How long is she staying in the US, visiting?

My Thai wife’s visa took 23 months not to bad really. Applied for her green card at the same time got it 3 weeks after we arrived in the mail as soon as she got the green card she applied for social security card got it within 2 weeks than got her a drivers license and her own bank account within 3 years time she got her visa green card, social security card, drivers license, bank account, job at Walmart, credit card, credit score, her own car and saves money each year to go back to Thailand for a month.

If you are over 50 go Non O

I did a DTV to be with my fiancé for now.

The CR1 visa can take between 8-14 months to process.

Apply for a non o 90 day over 50 retirement visa, no insurance or police checks. You can use the money in your home account as part of the application, much simpler than the non o-a you were looking at

Can you do a tourist visa then get a marriage visa when you arrive. You will need to show less

It sounds like you are trying to apply for a 12 month Non-OA visa which does require insurance, police checks, etc.

For a visa based on marriage you need to apply for a Non-O visa, from memory in the evisa app it's something like "stay with Thai family longer than 60 days"

You applied for non-OA. Needs insurance, police check etc. . Better to apply Non-O 90 day based on marriage ( marriage visa) and extend 12 months based on marriage, after you arrive. If you have Thai bank account you'll need 400,000 tbt in the account.
