How can someone obtain citizenship through the military? Is it possible?

It has been a minute or two since I retired. There was a program, MAVNI, which was based on which languages the Army/DOD needed. For example, I had some Mexicans that were in the states asking if they could join under the program. The Army has enough people who speak Spanish that it is not a language in demand. However, there was need for Chinese, some Mid-Eastern languages, and Korean. The best thing to do is contact a local recruiting office since these rules change all the time and the window when they open goes quick. If your cousin wants to do this and there is a need for her language, she needs to take the ASVAB, get physically qualified, and wait for the door to open. I had a Korean speaking applicant, who while on the Med line, Korean closed. It is that quick. Good luck.

A fast track citizenship program used to allow active duty military members to begin the naturalization process after only one day of active duty. I'm uncertain of the status of the program now, because it was amended under the previous administration. Check with US Citizen and Immigration Services.

There is a track to citizenship while serving in the military. However in order to enlist I. the military you have to have a ins-card. also known as a green card. you cannot just enlist to get citizenship, however if you are a green card holder and want to serve beyond 8 years you must become a citizen during that time
