If you have already been denied entry on the grounds that the immigration consider you to be misusing tourist schemes in order to obtain long-term stay in Thailand without the appropriate visa, the issuance of a tourist visa will not in itself guarantee that you will be permitted re-entry as a tourist. In such circumstances, I would recommend engaging an agent who provides so-called pre-scan or safe entry services, as they assume responsibility for your application and guarantee admission should they accept your case.
Thank you. If you’re having problems with opening a bank account @rudi you can apply for the one year extension of stay with a income affidavit from your embassy if you can meet the required minimum 65K baht a month without opening a bank account.
The Non O-A visa gives you a one year stay each time you enter Thailand within a year if you update your health insurance.
Therefore for your second year stay -after the visa itself is expired- you’ll need a re-entry permit in order to get stamped back in again on your stay.
It doesn’t say anything about this on the consulate’s website, so if you don’t get any concrete feedback, you’ll probably just have to contact them and ask.
It is impossible to open a bank account on your own without having a Non O visa or a long-stay permit. However, it is still possible to arrange it through an agent, such as the owners of this site. The price is currently around 60,000 baht for a bank account, a 90-day Non-O visa, and a one-year extension of stay. Alternatively, do as John suggests.
