Be careful about moving to a County like Nassau which has an expiring permit. According to the NYSP if you move back to Suffolk with a Nassau permit it is void when it expires and you have to reapply in Suffolk. One other thing, unless you reapply any restriction on your current permit will also be carried over to your new permit. Ain't NY great!
Your best bet is to call The Nassau PD and ask them because they may have some special procedures or rules when moving into the County.
www.troopers.state.ny.us/Firearms/FAQs/FAQindex.htmlQ - If a licensee was issued a renewable pistol permit and then relocates to a county where pistol permits are issued "good until revoked," does the pistol permit automatically become "good until revoked" upon transferring it to the new county?
No. While the Penal Law does provide for the transfer of licenses from one county to another, it does not permit the changing of the expiration date of the license when one has been assigned.
The license may be transferred and will remain in full effect until the expiration date has been reached. At that time the individual will become unlicensed, unless application has been made with the appropriate licensing authorities for a new "good until revoked" license.
