, you should have kor-3 already. The kor-2 is easy to get. The case is that if you dont have it and they ask for it, then you will have to go get it the same day, or you most likely will have to get a new bank statement. I am talking from experience. I always bring whatever possible.
, besides marriage certificate they will also ask for registration of marriage (kor-3) and confirmation of marriage (kor-2). Kor-3 came with the marriage certificate. Kor-2 should not be more than 6 months old from local Amphur.
, ok, thanks for the explanation. From a bureaucratic point of view, is raising a child the same as being married to a Thai National or more like a retirement visa?
