, no reason to worry if you leave the country before your visa expires, but as always no guarantee...

May 23 days, June 30 days, July 31 days, Aug 7 days. Total of 91 days.

@Håkan ******

, you mean Non-O extension?

@Kenny ******

, you are surely running out of luck very soon with this extensive travel history of staying in Thailand without a real visa.

ID card, yellow card, etc. depending on which country you are living? It needs to show your address.

The basic requirement for opening a bank account is to prove you have a solid reason for opening a bank account. Work, marriage, or "permanent stay" are such valid reasons. The last one is proven by a Resident Certificate from Immigration. Some Immigrations like BKK are very restrictive for issuing an RC, while others like Phuket and Chiang Mai are ready to issue an RC against even a TM30 from a hotel.

@Mal *******

, I guess you are correct.

@Steve *********

, yes, but the requirement of 800k three months before application and no less than 400k for the rest of the year only applies to the deposit method, not the monthly transfer/income method. But what if you combine those two methods?

You are obviously mixing the two very different methods for proof of funds, namely the deposit method and the monthly transfer method. What would be more interesting is to know what will be the requirement if you mix those two methods?

@Jody *******

, they will usually ask for the application for an extension about 1 month before the expiry of your current visa or visa extension but as everything else it depends on the Immigration office.
