If you are a green card holder, do you gain citizenship after completing Basic Combat Training?

Hi,

I'm a Green Card Holder with 5.5 Yrs of residence in the US, I'm in process in going active duty in the U.S. Army. There's some jobs that are not available for me, because of the "Secret Clearance". My recruiter told me that I can get my citizenship in the BCT Graduation or in a few months after the training; However, looking deeper in the Internet, some sites says "You will get your Citizenship after 180 Days of service.

Does someone have more information about this?



Thank You.
