Every time I have bought gold jewellery at different shops in Hua Hin and Cha Am I have had to show my passport if I am alone or my wife has had to provide identification if she is with me.
I guess it depends what you want. I opted for a marriage visa because I can work in Thailand with a valid work permit. I could have gone for the far easier retirement visa but I still have a few years of work left in me so why not. The pension will still be available in a few years.
Generally if all your documents are in order you should get a 3 month entry visa. I can’t say for sure but if you are using an agent then they know the system better.
In my situation I had to return 3 times before they accepted the documents. I didn’t use an agent in the process. My immigration office are stringent.
when you say start your marriage visa have you already provided all the documentation required?
The process I went through is make an appointment provide all the required documents this gets you 90 days. Then come back before the 90 days and provide all the documents again and then you get the under consideration stamp. Finally at the end of the under consideration you get the 1 year extension.
