My wife changed her first name because she was told it was more lucky for her. They get a certificate to show it's been changed.
Which name does it have on her ID card?
This was my message.
Royal Thai Embassy/ The Royal Thai Consulate-General would like to request for additional documents as follows:
Personal details of a family in Thailand, e.g. ID card, Passport and the visa page or stay permit in Thailand: - Wife’s Thai ID card or passport. Her name is not the same as your Marriage certificate.
