Hello, I’m taking my 16 year old son the the US go a month. 
 

He has both Thai and U.S. passports. 
 

Will I have any difficulty getting him checked-in, through immigration and on the aircraft without his mother?

 

What about leaving the U.S. or during transfers?

 

Thanks

CYA, as in cover your ass. Carry a note signed by mother permitting minor child to accompany you. I.d also have a copy of mothers passport page. 

Yeah I would bring a letter from mom, and copies of her ID and house book as well as your sons house book all signed by mom just to be safe.  I just flew with my half Thai baby and her mother but at immigration leaving Thailand mom went in a different line and didn’t wait for me, she was already around the corner when I got to the IO and they started to question me about it before I finally saw mom come back looking for us.

@mogandaveI took my 14 yo son to the US 3 yrs ago and he flew solo when he was 15. No issue, but he does have my surname. There was never a question. We flew to LA and then Denver on United. The next year he flew Qatar Air to Houston.

Show his US passport to check-in. Thai passport to exit and enter Thai immigration. US PP to enter USA. Check-in in USA coming to Thailand, use Thai passport; although, that really doesn't matter.

Thanks everyone, looks like mom changed her mind and wants to go now...

If you get the note or letter notarized at the US Embassy that's even better.
