Can a US citizen be denied a visa exemption stamp for entering Thailand more than twice in one year?

Pre-covid used to have 20 to 30 visa exempt entries a year when working outside. Never any issues.

If you have an outbound ticket then you should be OK. I used to visit 8-10 times a year. Rarely for more than a week and always with a return ticket.

the OLD rule was you could get two visa exempt entries per year entering by LAND, and there was no real official limit based on entering by air.

Given the current covid shit show going on along with the fact that land borders are closed AND the more stringent entry requirements I don't think you're gonna have any issues entering by air with a visa exempt entry for the foreseeable future

AND

if when you were stamping in you got grief, the next time you could get a tourist visa from the thai consulate in the US before you came again

>The embassy website says that the US visa exemption stamp is only granted to a person twice per year.

First rule to remember about visiting Thailand is never, ever, trust the information that's posted on your country's embassy website. They are always the last to know about changes, and they have no obligation to keep the information updated.

>My question is, has anyone here ever been denied for asking for the visa exemption stamp more than twice in one year?

IN PRE-COVID-19 days, a person is allowed TWO visa exempts by land in a calendar year, and "unlimited" visa exempts by air, until the immigration officer believes the unlimited visa exempts are being abused. Since COVID-19 happened, I have not heard of ANYONE being denied entry on a visa exempt yet.

>I believe I can apply for a visa based on marriage but the exemption stamp is pretty convenient and free.

It sounds like you're one of these people who work overseas, and visits Thailand once or twice a month. I highly recommend contacting your nearest Thai embassy and seeing if they sell a multiple entry Non-O visa based on marriage to a Thai national. This visa is valid for a year, and on each entry allows a person to stay for 90 days (so if timed correctly, you may be able to stay as much as 15 months or more). There has been no rejections on people entering multiple entry visas based on marriage to Thai nationals.
