@John *********
and with his apparent history of entries into Thailand as Visa Exempt with extensions... and now seeking to get a SETV single entry tourist visa, I see him being questioned by Thai immigration officers upon arrival into Thailand.
Brainstorming possible options and questions...
He needs to get the correct Thai Visa for his planned visits and stays in Thailand without the need to Play the Border Bounce games.
He's Australian ..
But has not said why he's entering Thailand so many times...
Does he have a Thai wife?
Is he the father of Thai child?
Has a girlfriend or other in Thailand?
What's his age? It appears from his photo that he is eligible for the retirement option.. 50+ ?
BTW...
The Thai Embassy and Consulate in Vietnam do grant the METV Multiple Entry Tourist Visa...
Suggest he apply for the METV and not the SETV...
