What is required to bring a firearm to the U.S. for hunting purposes?
Effective February 19, 2002, ATF requires nonimmigrant visitors entering the U.S. with firearms or ammunition to obtain a federal permit through ATF in advance of their arrival.
U.S. law also forbids certain nonimmigrant visitors, workers and students from buying guns and ammunition in the U.S. Diplomats, foreign law enforcement officials and visiting dignitaries designated by the U.S. Department of State are not exempt from this requirement when bringing a gun for hunting purposes.
You will need to obtain and complete ATF Form 6NIA (5330.3D Application/Permit for Temporary Importation of Firearms and Ammunition by Nonimmigrant Aliens) to apply for the ATF permit. You will also be required to obtain a license from any state in the U.S. where you intend to hunt. Please note that you may fax the ATF Form 6 NIA-5330.3D application to (304) 616-4554 for expedited processing.
You may contact ATF's Firearms and Explosives Import office by email at eps@atf.gov if you have additional questions. For more information about nonimmigrant visitors who wish to import firearms, please see ATF's Frequently Asked Questions.
