Citizenship issues encompass such things as citizenship at birth, citizenship acquired through parents, and naturalization.

With the single exception of qualification to become President, the law does not distinguish among categories of citizens. Indeed, there is only one "class" of United States citizen - irrespective of how citizenship is acquired.

Once acquired, United States citizenship remains effective unless formally renounced or revoked due to fraud. The only conclusive evidence of United States citizenship is a valid, unexpired United States passport. This evidence may not be challenged other than through a passport revocation hearing, initiated by the United States Department of State.
