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.
