In most cases, to hunt legally in the United States, you must have a hunting license from the state where the hunt occurs and comply with the state fish and game department requirements associated with that license limit. Hunting licenses can generally be purchased at any retail outlet that deals in hunting and fishing equipment, such as sporting goods stores.
The U.S. Fish and Wildlife Service manages an unparalleled network of public lands and waters called the National Wildlife Refuge System. With more than 560 refuges spanning the country, this system protects iconic species and provides some of the best wildlife viewing opportunities on Earth.
