Requires chief law enforcement officer or Superintendent of State Police to notify federal immigration authorities when non-citizen applies for firearms purchaser identification card or handgun purchase permit.

New Jersey's S 903 requires state law enforcement officers (specifically the chief law enforcement officer or Superintendent of State Police) to notify federal immigration authorities when a non-citizen applies for a firearms purchaser identification card or handgun purchase permit. This bill amends existing state law by adding a new notification obligation for these specific applications, directly affecting non-citizen residents seeking to purchase or possess firearms. The requirement applies during the standard background check process for firearm permits, where retailers already submit background check information to the State Police. The bill does not change eligibility criteria for permits but mandates an additional reporting step to federal immigration authorities for non-citizen applicants.
