My son and I are leaving Thailand and not coming back.

My son only has his Danish passport. His Thai one is expired.

Does he need to renew the Thai one to leave Thailand or is hos Thai id sufficient so he won't be stopped when flying out?

Just curious, If my visa extension ends on the 11th and I fly out the same day will I get a stamp that says overstay or will I be okay? TIA

I’m on amnesty atm and my last stamp was a 60 day visit family extension ontop of my last entry of a non o based on marriage me. I’ve just renewed my uk passport and I’m planning on leaving Thailand this month before the amnesty ends, do I need to go to immigration and transfer any stamps to my new passport or can I just roll on out of here by showing both passports to the io at the airport? Thanks
