Looks like everyone is foreign.
To take a bit of artistic liberty:
The "old" ones will have entered the US ions ago and gotten green cards or passports through their own means and the "younger" ones will have an F-1 visa from Ari Ben and have temporary status unless EFT has applied for and gotten them H1B work visas which are good for 6 years.
F8, another option for you I forgot to mention, enroll with a University and train and instruct in their aviation programs.
Some very good ones:
- University of North Dakota or UND
- Middle Tenessee State University or MTSU
