I assume if she wants to stay in Thailand.

Is she 18? Doesn't she hold two passports?

You need it retirement visit it's that simple and so does your wife I believe because she is also out of country passport. You have to show 800,000 baht in the bank every year you have to keep it in the account and be able to pay all your other bills of course.
