i don't believe that for a second. I know someone who gets yearly extensions based on retirement every year at the immigration office.
They show up, file ONE 90 day report (late), take the 2000baht fine, get the failure to file fined 2000baht stamp, then apply for their yearly extension and after that never go back to the immigration office the rest of the year
The next year they do it again, file a late 90 day report, take the 2000baht fine, then apply for their next yearly extension. They've done that 10+ years and have PAGES of failure to file 90 day reports on time fine stamps in their passport. They exit/re-enter the country on re-entry permits without any issue at all.
well if you're not married they're not getting a DTV based on "family of a DTV holder" that's just how it works out. They're going to apply for a DTV on their own and you having a DTV and being their un-wed partner isn't going to make a difference or not
Now as far as the sponsor letter saying you'll cover the proof of funds, you'd probably have to show that you have the funds for your DTV and for hers (so 1 million baht in the bank) BUT that's just a guess and I could be wrong
IF you fail to do a 90 day report on time and leave the country NOTHING HAPPENS, not when you stamp out (because officers at passport control don't care if you EVER did a 90 day report as it's not their job) AND not when you stamp back in ..
Now if you GO to an immigration office more than 7 days after a 90 day report is due to file one you will get a 2000baht fine and you will get a failure to file a 90 day report on time fine paid stamp in your passport
BUT
That stamp WILL NOT AFFECT YOU AT ALL, exiting or entering the country, ever..
So if you missed a 90 day report and exited the country you're fine
AND
if you filed a 90 day report late and got the 2000baht fine/stamp you're also fine.
You didn't enter with ANY work permit <- that doesn't let you IN or let you STAY, that lets you work and has nothing to do with your visa/extension in your passport
NOW if your work permit was cancelled you should have gone to the immigration office and cancelled the extension <- because one of the requirements for you to keep an extension based on employment is that you hold a work permit, so lose that, lose the extension.
You'll certainly get out okay..
I would guess you have an extension of stay good until 29 Jan 2026 w/a re-entry permit
If that's the case when you come back (as long as it's before 29 Jan) and you had a multiple re-entry permit you'd get stamped back in until the 29th of Jan again.
The officers at passport control stamping people in can't tell if you hold a valid work permit or not, they can only see the stamps in your passport
Once you get back you still need to go to the immigration office that issued your extension and cancel it
You won't be charged for an overstay of under 24 hours when you fly out <- they waive the overstay fine if it's under 24 hours, and if it's over 24 hours you pay for 2 days <- 1000baht
they couldn't have charged you because you stamp OUT after you check in for your flight, so you either stamped OUT of the country before 11:59PM or you didn't
definitely go for that 60 day visit family so you can season the funds and then you can apply for the year extension in country at your immigration office
When you get the 60 day visit family extension ask them for the hand out listing the requirements for the marriage extension at that particular office so you know what they want etc
your Non-O VISA expires Dec 26 or your current 90 day entry stamp FROM that visa runs out that date?
If you've had Non-O multi-visas any length of time you know you can get almost 15 months out of that visa by bouncing out/back just before the visa expires to get a final 90 day stamp.
So you're already ON a Non-O entry and you just don't have the funds seasoned the 2 months required to get the year extension from this entry.
Then the 60 day visit thai family extension will definitely "buy you the time" to get the funds seasoned
This is the clause in the police order that allows 60 days for the purpose of visiting thai family
