what benefit do you perceive from the pink card. I see no benefit from it other than *maybe* not having to get a residence certificate for certain things
Apply for the 90 day Non-O visa in the UK and when you return to Thailand open a bank account and place the funds required for an extension of stay in it. The funds must be in the account for 2 months before you can apply for an extension. If you need to leave during this initial 90 days you will need to get a re-entry permit. Once you apply for the extension your application will go under consideration for around a month and immigration may want to visit you at home and talk to your neighbours to ensure you actually live together then you go back and get the remainder of the 12 months stamped in your passport. Again you will need a re-entry permit if you want to leave and return
If you seriously don't want to put money in a Thai bank then look at getting a Non-OA visa, a 12 month visa which you can only get in your home country and using funds in your home country. It does require insurance, police checks etc though
You have to use your local Amphur, the yellow book doesn't do much to be honest other than sometimes saving the need to get a residence certificate from immigration
