the printout DTV clearly says "valid from" and "valid until". There is no text that says "visa must be used by"

between 7 and 15 days, depending they do not need to ask for more documentation

@Will ***********

you are spot on! This is the most obvious explanation

@Christopher **********

a DTV is a tourist visa type. It is almost impossible to find a bank willing to open an account to somebody on a tourist visa. You will succeed quicker if you go through an agent. It costs 5000.- THB for an agent's service in Pattaya to open a bank account

@James *******

are you really confusing a "visa" with a "stay permit"? You oughta know better

@James *******

It's the same game when transferring stamps from an old passport to a new passport. Immigration can only transfer their own stamps. The cannot transfer a visa sticker. Immigration cannot "cancel a visa". All they can do is cancel your stay permit, or refuse an extension of the stay permit. Visa are NOT issued under Immigration jurisdiction, except when you are applying for the "change of visa type" which actually is a change of the reason a visa was issued (or not issued when changing from a visa-exempt entry)

Immigration is not allowed to "cancel a visa". All they can do is refuse entry, and for this, they are supposed to show you the "Section 12" list of rules they claim you are violating. Immigration can only cancel "extensions". i.e. stay permits they have issued themselves. Visa are being issued by Thai embassies, and Immigration can't "cancel" or "invalidate" them. An embassy is ministry of foreign affairs, but Immigration is ministry of interior. None of these two bodies is allowed to touch a stay permit or a visa issued by the other one. If a visa has been issued, it is a done deal

with a multi entry visa, you could wait until the last 60 days within 8 months, before you apply for the "change of visa type". With a single entry visa, you application needs to be more speedier, as you can only apply as long as you still have a minimum of 15 workdays left on your 60-days stay permit
