Will I face an overstay fine when extending my 30-day visa exempt entry at IT Square Lak Si?

Just want to give people a follow up on what happened.

Despite having an uncancelled employment extension in his passport AND the dire warnings by people the O/P had NO ISSUES getting the 30 day extension on his 30 day visa exempt entry.

As I expected, they told him he'd only get that overstay fine IF he got a long term visa and went to get an extension <- which is when they'd assess the "overstay" fine.

He isn't really on overstay, as he's left the country and came back BUT overstay fines are the only thing immigration can fine you for in a situation where you didn't cancel an extension correctly. The fine will cap out after 40 days of 500baht a day or 20K baht AND when/if the O/P ever gets a job here they can worry about sorting it out.

On visa exempt entries OR even tourist visa entries it doesn't affect your ability to get the 30 day extension and they don't try to charge you for the "overstay" for not cancelling the previous employment extension.

SO all's well that ends well . . .

Congrats to the O/P for getting the extension (y)

You are highly unlikely to have any issue extending a 30 day visa exempt entry stamp at IT Square Laksi Plaza with an uncancelled previous employment extension in your passport.

That problem <- where you're fined for overstay because it's not cancelled correctly usually only comes up when you go to get a NEW Non-B visa or NEW extension based on employment/retirement/raising kids/married to a thai, etc

It does NOT come into play with 30 day extensions on visa exempt entries.

OR

As you mentioned in a previous comment before I flushed them all down the bin 😮 you could bounce out and back in to get your second visa exempt entry this year (that means you'd have no more free stamps by land this year) and get 45 days and then go get the 30 day extension on that stamp when it runs down.

The choice is yours. Either way you are HIGHLY UNLIKELY to have any issue getting a 30 day extension on either this current 30 day visa exempt entry OR the next one if you bounce out and back to get a 45 day stamp.

and on that note, so this doesn't go off the rails, we are done.
