I am on a retirement visa Type O. I’m 75 and already have an account with Bangkok Bank but I would like to open an account with KrungSri as a backup. I opened my account with Bangkok bank 22 years ago so I forgot the form number to request from Immigration when I go to do my 90 day. It would save me time if I know the form number. Thank you!

You want a letter of residence, it doesn't have a number.

Thank you very much!

You have non immigrant status.

To open a bank account best advised to visit bank.

Some banks may just require proof of address and of course passport.

If you rent then perhaps a lease. TDL. In recent times some banks (eg Kasikorn) have also required proof of an address in pp country.

In recent times some banks require a certificate of residence (COR)

KrungSri said I needed the form from Immigration but they didn’t know what it was called. Thank you!

Your welcome. You can download it here. Note this is for Bangkok, your local office may well have their own version.

Non-O base on retirement.

Krungsri (2 different branches) asked for embassy letter after looking in my pp. I could open a new (1st time) account. 1 year lease contract and a valid U.S. DL. No proof of address needed.

Some banks eg BBL ask for embassy letter or COR from immigration.

Some embassies no longer provide the "letter" you refer to.

As pointed out, the Letter of Residence (I think it also referred to as a COR - Certificate of Residence) is what you need.

... except ... except being if you have a Yellow Book instead of the COR - then that can typically be used instead. My recollection is when i opened up my Krungsri account, i provided my passport, and Yellow Book (and I may have also passed my 'pink-ID'). That was when I was on a Type-O visa.

That (yellow book) exception is likely NOT relevant to you.

Also, currently if on an LTR visa instead (AGAIN, clearly NOT your case) one also needs the "Notification of qualification endorsement for LTR" (from BoI) for holders of that visa to open an account.

Its a paper war . 😅

Think you will find they can be used for same/similar needs. ... eg TDL, open bank account etc however are different.

Upnotover posted form form "letter of residence"

I also posted link to form for COR.

Some recent other threads re open bank account have been possible with non immigrant status (Non O) + COR was accepted. A lease a bonus.

Aside: kasikorn apart what I posted is also now requiring proof of address in pp country.

A DL would be sufficient
