How can foreigners (non-United States citizens) join the Marine Corps?
Here is the criteria for an alien to join the U.S. Marine Corps: They must have entered the U.S. on either a permanent residence visa or an Alien Registration Receipt Card (INS Form 1-551/I-551 green card or stamped I-94). They must have established a bona fide residence in the United states. They must have established a home of record in the United States. Once in the United States and once all of the criteria is met, interested men and women can go see a United States Marine Corps recruiter who can help them enlist in the Marines or they can call 1-800-MARINES.
