Mohammed Saeed Alshamrani, a second lieutenant in the Saudi Air Force who was in the US as an aviation student, was able to buy a gun despite the fact that “nonimmigrant aliens” are not permitted to do so, according to NBC News.
The BATF notes that anyone admitted to the US under a nonimmigrant visa is typically “prohibited from shipping, transporting, receiving, or possessing a firearm or ammunition,” however, those with a valid hunting license or permit, and those who were admitted for “lawful hunting or sporting purposes” are able to purchase firearms.
Alshamrani was able to get such a license, according to sources cited by NBC, allowing him to undergo a background check, which in Florida involves a three-day waiting period, per state law.
The Washington Post further notes that another ATF regulation allows non-citizens to possess firearms if they’re from “a friendly foreign government entering the United States on official law enforcement business.”
