I say let the guy stay and do his job. The US military is perfectly willing to grant citizenship to immigrant volunteers for their service as is the college system with its immigrant recruitment flexibility. Anyone so desperate to become a US citizen in the face of a system that defies legal immigration through an antiquated and discriminatory quota allowance is the type of citizen the US needs. I watch slap on the hand law enforcement and judicial proceedings occur on a regular basis when such actions benefit society as a whole. This guy should be included in that flexibility.
