Need a firearms license? Mail it in

New York City has the toughest gun laws in the country — but if the proposed conceal carry legislation passes through Congress and is signed by the president, Big Apple residents can get a permit from a handful of states without even leaving home.

States that allow permits by mail include Arizona, Florida, Maine, New Hampshire, Utah and Virginia, according to Handgunlaw.us, a pro-gun Web site that tracks laws in all 50 states.

In all six, anyone living anywhere in the US can apply for a permit by mail, with some even offering them to legal residents from other countries.

New Yorkers can also get permits from 20 other states that don’t require residency, although they mandate the applicants appear in person to pick them up.

The costs vary, but on average appear to run about $100.

Each of the states that allow permits by mail has differing standards — some of them tougher than others.

In Arizona, for example, even “permanent resident aliens” can qualify if they prove their residency status is legit.

Convicted felons or those convicted of any domestic violence crime are not eligible.

Neither are those who have been committed to a mental institution.

In Florida and some of the other states, the appli- cant has to prove that he or she has received firearms training.

Most states also require fingerprinting and valid identification.

Many of the states already have reciprocity agreements with other places. Arizona permit holders, for example, can pack heat legally in 31 other states.
