I am planning to get married with my Thai girlfriend. As I am from Nepal, it takes longer time to get it done. 15 days quarantine and 45 days for marriage registration won't be enough and I don't want to get back Nepal as there is no direct flight yet. Transit flight cost is quite high. If it's possible I want to stay longer till we receive marriage certificate then I will go back Nepal to apply Non-O marriage visa. Kindly suggest.
