With a residence certificate from immigration some banks might open an account. Bangkok Bank will typically do so with the purchase of a one year accident insurance policy. Many banks flat out no without a work permit. It will vary bank to bank, branch to branch.

30 day visa exempt and can extend

30 days once here

Russell Blake is it ok if I send you a pm?

You just need money in bank to apply non O in Thailand does not have to be in bank for 2 months but it has to be in 2 months for retirement extension then also has to remain for first 3 months of retirement extension

Russell Blake where in Thailand do you plan to live? A few things may differ slightly by area but this website helpful to explain

You don't have to leave country, apply for 90 non 0 once funds in account then last 30 days when funds have remained in bank 60 days untouched then apply 12 month extension for retirement

Paul Darby non O-A outside Thailand and Non O in Thailand both with retirement extension? So either way not really called Retirement Visa yet serves same purpose?

Believe in addition to Wayne Roberts 2 items you also need one 4 cm x 6 cm photo

I explained in my first comment believe you can get a 30 day extension at immigration

We are Canadian arrived visa exempt and were able to get 30 day extension. It's with your passport and other paperwork. Look up the immigration office in your area, go see them or call to find out. This all is not to do with Thailand pass...two separate things. Thailand pass is needed to enter country but once in Thailand it is not what is extended. It's a stamp in your passport with a new date you need from immigration office if eligible.
