If an immigrant served in the U.S. military during a time of hostility, then they may be eligible for expedited naturalization. Times of hostility may include September 11, 2001, World War II, the Korean War, the Vietnam War, etc.
The restrictions loosen for those who are eligible for expedited naturalization. For example, the naturalization applicant may not be required to undergo the period of continuous residency or physical presence requirements.
Naturalization applicants will still need to meet the following requirements:
Be of good moral character;
Know basic English;
Pass the U.S. civics test; and
Take the Oath of Allegiance to the United States.
When applying for naturalization, eligible applicants will need to prepare and file the form N-400, Application for Naturalization. Their application must also include forms and documents that verify their military service.
Spouses and children of members of the U.S. Military are also eligible for immigration benefits, such as being granted parole-in-place.
Parole-in-place allows for foreign nationals who entered the United States without authorization or inspection by an immigration officer to adjust their status to permanent residents without the need to leave the United States.
Additionally, if the person serving in the military is deployed abroad, certain dependents may be eligible for expedited naturalization and/or for overseas processing.
