Thank you all for your replies. I can handle the 800,000 baht for a retirement visa.
Is this a feasible strategy:
She and I apply for 60-day tourist visas and arrive in early December. We both get 30-day extensions. That would take us to the end of February. By then, I would be 50 and we could be married. Then, I apply for a retirement visa, which she piggybacks onto.
Is that unrealistic? Since she’s a Burmese citizen, I’m not sure how easily she can get any type of visa for Thailand.
Please feel free to offer any suggestions or tips.
