Do we not do the same thing with the military, and then as part of their service, help them to qualify as citizens?

No, the foreigners in the military must first be LEGAL IMMIGRANTS and have an IMMIGRATION VISA.

Only way to be an immigrant, in fact, is to have an immigration visa. Otherwise you are just another foreign visitor whose purpose is to leave her and go back home.

According to my sources:
A non-citizen that is eligible to join the military must meet certain requirements: (1) Have an Alien Registration Receipt Card (stamped I-94 or I-551 Green card/INS Form 1-551), (2) Have a bona fide residence established, and (3) Have established a record of the U.S. as their home.
