It’s just proof that you’re in Vietnam whilst applying for the DTV
What people usually provide as that proof is; the entry stamp in their passport from Vietnam immigration at the airport. Their boarding pass from the airline, and their accommodation proof, which an AirBnB booking/receipt is.
If you are in the country for 90 consecutive days you report that fact to your immigration office (your TM30 designated which office is ‘yours’). That is what a 90 day report is.
If you’re not in the country for 90 consecutive days, then you don’t.
Anonymous participant 648 it’s quite likely that your ‘visa’ is in fact an extension of stay now.
Your initial 90 day visa did indeed work like that. It had a validity period (valid from <date> to <date>) and you would get a 90 day stamp at immigration when you entered the country during that period.
Now you’re on extensions your re entry permit gets you stamped in till the end date of that extension.
Lots of speculation in this thread about what the DTV is, what it’s meant to be, what it’s going to be etc etc.
you’ve been asked a question by the consulate. You must have a plan as to how you’re going to sustain yourself whilst in Thailand. You’re going to live off your savings.
The first requirement is that a TM30 needs to be filed within 24 hours of arrival at any property you’re staying at (hotels usually do this for you without you realising, longer term residences, not so much) then on day 89 (your arrival day is day one) your 90 day report will be due. You can report that in person two weeks before the due date and up to one week after it.
The advice normally given to anyone who is about to apply for any kind of extension at an immigration office (apart from maybe a 30 day extension on a tourist visa/visa exempt) is to GO to the office you’re going to use way before you apply and ask them IN DETAIL exactly what they will require for that extension.
They’re happy to tell you so that when you do apply for the extension, you don’t waste anyone’s time (yours included) and it all goes smoothly.
It’s less frustrating if you do that, plus you’ve got time to get anything you’re missing before your stamp gets close to running out.
