What if I did not have a license in my home country and wanted to obtain a New York State driver's license, is there any way to facilitate the license process by showing the previous one?
In that case you would have to pass a written test, complete a 5-hour pre-licensing course and pass a road test.
ok, now regarding the driver's license, if i live in two states should i change my license?
No, you do not need to apply for a New York State driver license until you become a New York State resident.
