My girlfriend is from Laos, divorced from her Thai husband. Her son is legally Thai and in university in Thailand. She wants to visit him regularly for long periods. I see posts here about people using Savanakhet as an easy path to continue a marriage visa. Is that an option for her? What are her options to visit her son? And what should she expect as a financial requirement? 400,000 TB in an account? And what is that visa called? Many thanks.
