thank you so much for researching this for me. Robert Lagas said that I would be overstaying if I don’t leave Thailand the day my school year ends. And I have no possibility to get married sooner (before 15th of May) because of my embassy. It seems that I will have to leave anyway just to buy some time.
I’ll for sure get the letter and an appointment slip at district office if possible. My boyfriend also wants to come with me on this journey to give moral support:D thank you for your advice:)
