The ATF has updated their policy so non-citizens can purchase firearms

The ATF has updated their background policy and non-citizens can purchase firearms in some states.

From the California Attorney General's office: “A valid Alien Registration or I-94 card is required at the time of purchase of any firearm. Non-U.S. citizen applicants must also meet certain federal requirements to purchase a firearm, unrelated to the firearms eligibility background check.”

From the ATF: “An alien legally in the U.S. is not prohibited from purchasing firearms unless the alien is admitted into the U.S. under a nonimmigrant visa and does not meet one of the exceptions as provided in 18 U.S.C. 922(y)(2), such as possession of a valid hunting license or permit.
