I'm interested in knowing more about a foreigner being able to open a Thai bank account with only a tourist Visa

On the Bangkok bank website it seems to indicate that you can I have attached the requirements that they show on their website

A couple of things I don't know is;

one how to apply and can you do it online

I didn't see anywhere on the site that indicated you could

The other thing I need to know is the reference letter from the foreign bank or my bank in Canada it seems to say it needs to be sent by swift code

I don't know if I totally understand what format that reference letter needs to take and how to send
