the embassy's website is the best source of information as to what is required.

@Bart *******

you can apply at the immigration office in the province/city you're registered in

Buy plane ticket out of Thailand, then when you want to return meet all the requirements to get a COE, then get on the plane back.

Only if the unable to travel due to covid extension is still available. Otherwise you'll need a proper visa.

The easiest way to prolong your stay is to get a tourist visa before entering Thailand, this is for 60 days instead of the 30 days the visa exemption gives you.

@Bart *******

yes, then if the 60 day option for having a Thai family is available then it avoids the need to apply for the non-O. I'm not sure on the 60 day option here so will leave someone with more knowledge than me explain.

Alternatively, visa exempt for 30 days then apply for the non-O in Thailand to give 120 days

@Bart *******

tourist visa will give you 60 days plus you can then get a 30 day extension in Thailand for 1,900 baht.

@Bart *******

OK, in which case if you want to stay for 110 days don't apply. Either arrive on visa exempt or apply for a tourist visa, you have a choice to then either extend this by an additional 30 days in country and/or or apply for a non-O once in Thailand. This takes you beyond your 110 days.

Someone may also correct me if I'm wrong but I believe there's also a 60 day visa available for having a Thai wife but as I'm not 100% certain on that I'll leave someone like Tod to clarify that should he see this post.

Do you already have your non-O visa/extension of stay or will you be applying for it before you leave for Thailand?

Yes you can enter on visa exempt or tourist visa and switch to a non-O if you meet the conditions.

each to their own, personally I'd just go and get the stamp for peace of mind
