If you become a resident of NYS, you must apply for a NYS driver license not more than 30 days after you become a NYS resident.
You can exchange an out-of-state driver license or Canadian driver license for a NYS driver license if the driver license has your photograph, the driver license is not suspended or revoked and the driver license:
has been valid for at least 6 months, or
has expired in the past 12 months, or
is a valid CDL and has been valid for any amount of time, and
The driver license that you exchange must show the date that your driver license was issued. The date is required to verify that the driver license was issued at least six months before you applied for a NYS driver license. If your out-of-state photo driver license does not show the date of issue, get a driver license record or letter from the state that issued the driver license that indicates the date of issue. The letter or driver record must be an original and must be on the letterhead of the Department of Motor Vehicles of the other state. The letter or driver abstract cannot be a copy or a fax.
