If your CIP requires a foreign passport or I-94 documentation for a resident alien (green card in hand) then its author was sorely confused and the program needs to be revised. A resident alien has a right to be in the U.S. regardless of her country of origin and she may no longer have a current foreign passport.
Risk ratings are subjective and are entirely an internal matter. While you may be required to produce a list of non U.S. persons in an expanded BSA examination, there is no assumption regarding the appropriate level of AML risk they represent.
