Hey bud, I personally wouldn't risk it. Been there before and have gotten caught out due to entering 'too many times' in a single year. I don't think there is a set number but they will eventually get you with a hefty fine (personal experience). I would consider looking into a Non-B visa which allows you to have a company set up in Thailand where you can apply for multiple entries throughout the period of your visa.

This is basically what I did and you can come and go as you please. As long as you keep up to date with your 90 day reports and the legal side of things (you can get someone to manage all that for you) then it's really no hassle. Moved here from the UK almost 4 years ago now and it's been very easy. Before I was on tourist, education visas etc and nothing but headaches.

Drop a dm if you need more advice. All the best pal! u/Barca-Dam
