Can I convert from a Non-O retirement extension to a Non-O marriage visa without leaving Thailand?

@Anthony *****

Each office have their own interpretation.

Ross Parkes Go figure?

So weird. I was told by Trat Immigration that because I had an OA retirement visa I would have to leave Thailand and return but if I had an O visa I could convert there and then to a marriage O if I had all the correct paperwork?

if you have done the marriage/Thai wife extension before, then there is no reason to waste money on an agent to help you. If this is the same wife, and you kept your old documents, then you only need two documents updated, your bank letters, and passbook copies, and your pictures. Everything else is the same. It is good to go in a little more than 30 days before your current extension expires, as you'll have the 30 day under consideration stamp, then your new extension will be dated from the expiration date of your retirement extension.

If you're going to "push your own paper" <- go to the immigration office and get your own extension, then definitely go out there well before with your wife and get the scoop on things there at your office. People bitch, piss and moan about doing that but it really DOES pay off rather than showing up with half of what you need on the day you're applying for the extension
