Brief background: 23yr old, born overseas, citizen and grew up in the United States. Attended college and graduated. Immediate family are all U.S citizens expect for mother who doesn't want it because the process is too cumbersome for her.
The problem: The individual wants to work in the intelligence community and find as much success as talent, effort and knowledge will allow. However, Intelligence community has strict policies that prevent anyone with "immediate" family who are not U.S citizens from gaining jobs, security clearances or advancing. This applies to individual since his mother is not a U.S citizen nor will she ever apply to become a citizen (despite being eligible for the past 7 years). Individual finds policy unfair since it bases his ability and candidacy on the actions of another (In this case his mother).
The Question: Is such a policy lawful? Does individual have ground to challenge such a policy?
