Many MANY hundreds of people the world over have gotten their DTV's rejected because the MRZ on their passport when they scanned it didn't auto fill correctly on the application and they never checked the data entry carefully before submitting the application 😮
Some re-applied the second they found out they were rejected and ended up getting approved no problem
What's the "fly to Hanoi and re-apply"? why do that? It's just middle of June, if you're not leaving until Aug 1st apply again right now, CHECK the data carefully before you submit the application. You'll get the DTV issued in plenty of time
I got my months mixed up (seeing as this is JUNE) you won't be going to the US until April NEXT YEAR <- after you get your next yearly extension. 🙂 😛 so just buy the re-entry permit then when you get the new extension and you'll be good to travel during that year
I would say if you looked at the stamp in your passport it would read as "extension of stay permitted until" and have a date of August 2025 <- meaning you are on a yearly extension of stay
Now to leave the country and come back without cancelling that stamp when you exit the country you need to buy a "re-entry permit". You can do that at the immigration office where you got your extension issued OR at the airport before you fly out.
A single re-entry permit (lets you leave/come back once) is 1000baht and a multiple re-entry permit (lets you leave/come back as much as you want during your stamp) is 3800baht. Re-entry permits are valid as long as your current stamp is (so if you bought one it'd be good until Aug 2026 just like your next extension would be valid for)
As you're only going to the states once in April, then will be getting a new yearly extension in Aug a single re-entry permit would work for you.
so after you corrected it the first time, saved your application, then went back to finish it and submit it, it had changed it back to the wrong data it scanned from the MRZ line of your passport? 😮
