How To Change License From Nj To Ny Driver's License In NY/NJ Questions?

Driver's License in NY/NJ questions? - how to change license from nj to ny

This is a fairly large, long-term problem with a couple of pieces:

1.I M '19 .. I still have the permission for the reasons to buy are not really important. I want here in New Jersey is this or next week. I'm legal, I'm sure I would have to wait 3 months until my NJ license to receive, is not it? And when I leave to the legal?

2. In 365 days I have moved out of state are in the area of Long Iceland. I want to change my license at the time, and is there anything I should do, how I will live there in that place and time?
