Definitely a lack of planning on my part, I was under the assumption there would be a service I could basically throw money at to fix the problem. I don't have a bank account, but a visa service said they could help me open one for ~10,000 baht (I don't remember the figure).
My plans for my stay is to make it as permanent as possible. Will a Non-O marriage visa allow me to stay year round? Can I then just apply for Non-O every year and stay permanently?
From what I can glean, it looks like my timeline is this:
1. Re-enter the country on visa-exempt this month.
2. In this visa's time, get married. I realize this has a lot of steps, I'm most likely going to use a service that will help me. My partner if from Nakhon Sawan, if that information is relevant.
3. It was said that I can turn a visa-exempt into a Non-o. I think this requires a bank account, which I do not have. I suspect this is why Rob Browder says I would need to leave the country to get a Non-o first. That would allow me to open a bank account, and then get the 1 year extension. I contacted a visa/immigration business that has a service to open a bank account even under visa exempt, which I may end up doing.
I don't mind if I have to re-enter the country another time to make all the steps work, but I prefer not to leave the country.
Should I be opening the bank account as soon as possible? The visa service said that Thailand no longer allows foreigners to open a bank account under a visa-exempt, but I can't get a non-o until I'm married, correct? If I have to have a bank account open with 400,000 baht inside of it for 2 months, is that my first concern?
Thank you for all the advice, guys. If I'm missing something here, please let me know.
