How do you get a green card to join the U.S. Marine Corps?

You must obtain a green card through regular channels prior to enlisting in the U.S. Marine Corps as the law restricts the military from recruiting or assisting the immigration of foreign nationals, explains the Houston Chronicle. To apply, fill out Form I-485, available at the U.S. Citizenship and Immigration Services website. The United States typically grants green cards for relatives of U.S. citizens who an employer or family member sponsors, according to U.S. Citizenship and Immigration Services.

The U.S. Congress limits the number of visas available each year, with the exception of visas for parents, spouses and unmarried minor children of U.S. citizens, states U.S. Citizenship and Immigration Services. These immediate family members can apply for green cards without restrictions or waiting periods. Other family members, such as unmarried adult children of U.S. citizens and spouses of permanent residents, are eligible for visas but must apply for one from the limited pool. Congress also limits the number of visas available to employees, and the U.S. Citizenship and Immigration Services gives preference to uniquely skilled and educated workers.

Legal resident aliens can enlist in the Marine Corps, but only citizens are eligible for officer ranks, states the Houston Chronicle. You must also be between 17 and 29 years old, fluent in English, physically fit, and possess a high school diploma or equivalent.
