Depends on the state for the boat. In PA as long as the boat is registerd your ok but each state has there own regs. Yes you will need an out of state fishing licence & thats why the pro's have so many sponsors!!
More important make sure you have the state & coast gaurd required equipment on your boat PFDS, FLARES, AUDIBLE, THROWABLE CUSHION, EXTINGUSHER YATA YATA YATA & so on!!
If you've never been down here you might realize why we love to come up there!!
