Yes, you can apply for a 90 days Non O visa based on marriage at the immigration in Thailand first and one year extension of stay after 90 days.

This is as Brandon states only a six months multiple entries tourist visa which gives you 60 days upon each entry within six months, -NOT a one year Non O-A visa.

If you have a Mexican (or Canadian) passport you’re entitled to a 60 days visa exemption and free stamp upon arrival. Your previous travel history seems quite clean, and nothing indicates that you’re not still just a genuine tourist.

Be aware of that’s it’s a formal requirement for visa exemption entries to show proof of an onward ticket within 60 days regardless if you plan to apply for a 30 days extension.

Better to take your earnings yourself then maybe? It’s just the first year for five months you have to tie up 800K baht to play by the rules in Thailand and get a legitimate stay. For all the coming extension of stay you’ll need to pay your agent what they charge to do illegal bypass instead of the 1900 baht fee and something you easily can do yourself in 30 min.

Agree, it’s gambling

Formally you’ll need a ticket out of Thailand within 60 days when you re-enter on another visa exemption. Some of the airlines in Vietnam are known to be quite strict regarding this.

I don’t know when you have your return to the UK if that’s the case, but the requirements are an onward ticket out of Thailand, never a return ticket.

Don’t have any experience flying with EVA, but formally an onward ticket is required within the days you’ll get stamped in for at the immigration. At the Thai embassy in London’s website is stated that a bus ticket is sufficient. The Ministry of Foreign Affairs requires an “air ticket paid in full” and the Royal Thai Police Immigration requires “such as an airplane ticket.

I know several people are allowed boarding with a bus ticket without any issues, some are allowed after some discussion, but I’ve also seen some feedbacks of people denied check in only with an onward bus ticket.

Formally you'll don't need a return ticket, but a ticket out of Thailand within 60 days if you enter on visa exemption. Travelling from US without checking this further up is sort of gambling.

Ok, six months multiple entries tourist visa then, but it still only gives you 60 days upon entry and you can apply for a 30 days extension at your local immigration.

If you have a tourist visa it only gives you 60 days upon entry, 90 days is only related to the visa's validity days after issue. You’ll not be asked for the purpose of your visit.
