I have a friend who is an illegal immigrant.
We live on the West Coast & would like to vacation to the East Coast.
To do this we'd like to take a plane.
He has a school ID, birth certificate from his native country (Mexico), & an ID from his consolate.
Are these documents sufficient for boarding a plane?
Does he need a Mexican passport to travel on the plane going from one side of this country to the other?
Is there a risk of him being deported by trying to board the plane?
Thanks for your time
