Will my partner face visa issues for visiting Thailand every month?

I am going to caution people one last time to NOT bother posting things like "I've flown in and out of thailand for years every month on visa exempt entries and no one said anything to me..."

It gives people a false sense of security. I mean just because you managed to do it does NOT mean that every does.

IF you have an extensive entry history to thailand (especially living here on back-2-back visa exempt or tourist visa entries) about all you can do is be prepared with the proof of funds, proof of onward travel and proof of a hotel booking..

You might skate thru and you might get questioned. It comes down to the immigration officer you're standing in front of when you stamp in.

About all they do is be prepared as far as having proof of funds (20K baht or the equivalent) in CASH, proof of onward travel and proof of a hotel booking.. Have those things and hope for the best :)

What nationality is your partner? I would guess they're entering the country on a visa exempt entry?

No one can predict IF your partner will or won't get questioned by the immigration officer when they stamp into the country.
