ok then enter VISA exempt for 60 days and forget the 90-day Non O based on family. If you change your mine enter with Non O based on Family and get 12 month Extension 12-months for ฿1900. Then you can have your bank account
yeh but that's a problem as you I'm assuming don't have a Long Term Visa . But if you have the bank tru and see if they do. Insurance you will need so give that a try
ok if your on the 90-day Visa based on family you may be granted a 12-month extension of stay. Your extension of stay will start after your visa expires
If your visa is based on a marriage, and your spouse dies, you can remain in Thailand until the end of your extension. After that you either need to apply for an extension based on a new reason, or leave Thailand.
firstly unless you applied for a visa before you travelled you don't have any visa but you are stamped in for 60 days Visa Exempt. Now yes this is enough time to convert to a Non O. However there are reports you might not be able to get a bank account to park your money. Do you have a bank account?
