It appears the O/P did NOT follow the seasoning requirements for the extension they're on < letting the balance go below 800K during the 3 months after the extension was granted.

Now at this time they're unlikely to have any issue and BUT when they go back to the immigration office next year to apply for a new yearly extension of stay believe me Immigrations WILL see that the seasoning terms were not followed.

AND

As was pointed out, 'technically' you void your extension the day you fail to follow the seasoning (meaning you were in theory on overstay since that date) <- this is IF the immigration office wants to take a hard line stance.

Sadly for the O/P there is no way to 'restart' inside the country.

You'd have to leave the country, (getting off the current extension), then get a new 90 day Non-O visa at a thai consulate in a nearby country, come back and 2 months later apply for the yearly extension

OR

exit (getting off the current extension) /re-enter the country on a 60 day visa exempt entry ,then apply first for the 90 day Non-O visa and after that the year extension

I would say you run almost a 100% chance that immigrations will notice the shortfall in your balance <- that's why you have to get a year detail transaction report, so they can see the balance on the account every transaction during the year to verify you followed the seasoning.

I would definitely be planning you're going to have to start the whole process all over from scratch

careful saying 60 days, because the rule is written as 2 months and often times 2 months is MORE than 60 days 😉

For the OA visa it's "Those who wish to stay in thailand no longer than 1 year (multiple entries)"

You get this pop up telling you it's an OA

For the OX visa it is just the choice "Those who wish to stay in thailand for 5+5 years (multiple entry)"

You get this pop up telling you it's an OX

Also comes up with this pop up when you select where you are

@Ron *****

thanks for that. Appreciate the info..

@Ron *****

and you are speaking from experience, having used this form at the immigration office where you get your yearly extension?

@Pho *******

there is no requirement that the funds come from abroad when you get a yearly extension based on retirement

your data in the middle, family member on the top, immigration officer signs it, never seen that anyone had to witness it before

they started handing those out in Bangkok this last year for marriage/raising child extensions

is it this form?
