You must exchange your driver license from another U.S. state or territory, federal district or Canadian province within 30 days of becoming a  New York state resident.
Are there exceptions to this rule?
Are you a student studying in New York State?
Yes I am.
Students from elsewhere are normally not considered residents of New York State, so they don t need to exchange their current driver's license.
If I do end up quitting school here and becoming a resident of NY, what if I go back to Canada and need my original driver's license?
In that case, when you pass your road test, ask the road test examiner how to make sure that your foreign driver license is not destroyed.
How will I prove that I'm a resident if I still pay taxes in Canada?
Normally, a judge considers these facts to decide if your intent is to make NYS a "fixed and permanent" residence.
I've been here 3 months and I got a ticket the other day. I still use my Ontario driver's license, how does that affect me?
A police officer can use this as evidence to issue a traffic ticket if you drive in New York State without a New York State driver license or vehicle registration. If you contest thew ticket, the judge will examine your evidence of intent and decides according to the law.
There's no date on my license of when I got it, what do I do?
