there have now been several reports that Immigration wants the proof of 500.000 THB in your bank account, again, if you opt for the extension. So you are better off to bounce as by the border nobody will ask you for your bank account detail
well as long as he fulfills the 6-month minimum validity, he will get stamped in . . or, in other word, with a 6-month validity, the airline will allow him to board a flight
*** you will get your DTV approved by the embassy or consulate, as long as your passport still has a validity of more than six months, and the same applies on every entry - the 6 months validity is a requirement.
(something that slipped through the grapevine but what is actually and factually required)
*** now there is this thing, when you get issued a new passport by your embassy , while you are still inside Thailand, you need to ask them to give you back your old, though invalidated passport.
Because Immigration is going to move the entry stamp from the old passport to the new passport.
*** when entering Thailand in order to receive another 180 days, you will not only need to show the pdf visa document to the border official, but also show him your old passport
BECAUSE YOUR DTV got issued on the old passport number!
You will get stamped in for 180 days in your new passport, but they will not change any detail of your DTV visa document.
Immigration in Thailand is not allowed to touch anything that got issued by the Ministry of Foreign Affairs = embassies and consulates. That’s why you need to keep your old passport on you all the time when you re-enter or extend
