Afternoon guys, I need a little advice if possible from anyone familiar with Jontiem immigration.

I’ve still 3 weeks on my visa and wish to extend it 30 days ( which I’m entitled too😇)

What is the specific counter I go to & do I register or fill anything in first?

I popped down for a look the other day & didn’t see any obvious signs… the Q at the information desk had around 30 people in and snaking out the door!

Thanks in advance and for previous spot on advice 🙏🏻

I just got a new passport so I'm going to go to immigration to have my current stamps transferred over. Is there any documentation I need to do this, other than the new and old passports?
