What are the best visa options for a 94-day stay in Thailand?

60 day TR then border run

Easy! Get ya 2 month tourist, when in Lipe, go to Langkawi, get 30 days on arrival on the way back to TH, 1 week before your 30 days is up in TH, go to immigration, pay 1,900 and get another 30 days.

, SO much 'problems' for those extra 4 days !! Why not just 90 days (you say you haven't book y'r ticket yet). But.....maybe you have y'r reasons 🤷‍♂️

As others have said, if you've booked already 94 days is not ideal. One option, if you're over 50 is the o-a visa if you really want to remain in thailand the whole time and don't want to bother with immigration visits. The best alternative would probably be 60 day tourist, a few days in Vietnam or Cambodia and then re-enter again on visa exempt

The 90 day non O will give you just that. 90 days. It’s not extendable unless you want to do so for a year and meet the financial requirements. You can only get one extension off a tourist visa or visa exempt entry. Sure you can hop to a nearby country and get another tourist visa or enter exempt again. Will probably be easier than applying for a non O, which wouldn’t give you the time you want anyway.

You picked a trip duration that basically guarantees you'll need to do a border run.

If you get a Tourist visa before you come to Thailand, you will get 60 days in Thailand and you can get a 30 day extension, giving you 90 days, but then you would need to leave and re-enter to get more time.

If you just come without a visa and do visa exempt, you will get 30 days in Thailand which you can extend for 30 more days, then you would need to leave Thailand and re-enter to get 30 more days, which you could extend again at immigration.

If you get a Non-O before you come, it will only be valid for 90 days and you'll either need to apply for a 1 year extension, or leave and re-enter the country.
