My gf is, Philippino and hoping to come Thailand soon on 45 day visa exempt.

Can she extend by 30 days at the end of the 45 days?

I entered Thailand on the 60 day SETV. I had asked immigration if I could enter on the exemption because my plans changed and I need to leave within a few weeks and will come back before the initial 90 days are up.

He didn’t answer me, but I received the TR stamp with 60 days.

-> But he did NOT stamp my visa “used”

... will I get to enter on it again? Or should I get a reentry permit and not risk it?

(I won’t be gone long and I need this visa type to get certain things done that are easier than being on an exemption).

Im in chang mai now but in samut prakan just out side of Bangkok i was told i had to provide a rental agreement to get an extension wich is hard because ive used air bnb to book my rooms for the next month. Is the rental agreement needed all over? Also id hoped to get a 60 day visa but they made it seem like i could only extend my exemption for 30 more days. Im confused by everything i read online so i hope to get some straight answers on here. Any help is greatly appreciated as ive used 2 weeks in Bangkok so i have to move quickly. Tia
