You can get a nonresident permit from Florida or Utah and legally carry concealed in Delaware.
I was told that a non resident permit from Florida or Utah will not work.
Non Resident only works for the state applied for.
Can someone correct me on this?
Yes, Delaware is not one of those states that require you to be a resident of the state whose permit they honor. Those states are: Colorado, West Virginia, Florida, New Hampshire, Michigan, South Carolina, and Kansas. Check out http://www.handgunlaw.us/
Florida and Utah permits are good in Delaware. I'm waiting on a Utah permit to be legal in Delaware and several other states where my PA permit is not recognized.
