Do save the printout of the Evisa for if/when you want to extend your stay another 30 days in country because the immigration office will likely ask for a copy. 😉
There's no such thing as a 45 day tourist visa for anyone. It's a visa exempt entry. 🙃 Each visa exempt entry may only be extended once. Cost of 1900 thb at residing immigration office.
As always, one is always at the discretion of the officer in front of you.
