For Gun Control Act (GCA) purposes, a person is a resident of a State in which he or she is present with the intention of making a home in that State. The State of residence for a corporation or other business entity is the State where it maintains a place of business. A member of the Armed Forces on active duty is a resident of the State in which his or her or her permanent duty station is located. If a member of the Armed Forces maintains a home in one State and the member’s permanent duty station is in a nearby State to which he or she or she commutes each day, then the member has two States of residence and may purchase a firearm in either the State where the duty station is located or the State where the home is maintained.
