Hello

We are in need of an urgent advice and any help is highly appreciated.

My wife and I are both foreigners with Non B and Non O.

Our son was born here in Thailand (2023) and has a passport but not a Thai visa yet.

We are having an unexpected 3 days trip abroad that let us with not enough time for my son to apply for a Non O.

As our home country is entitled for Visa on Arrival (not visa exemption) for a 15 days stay what could be our choices?

Can our son be stamped to such 15 days on arrival and then do overstay? And in this case would he need to show a departure flight? Will he be stamped overstay?

I've heard there is no issue for children from countries under Visa Exemption but i am not sure about countries under Visa on Arrival.

Thank you very much for your kind help.
