And what should I do if my visitor status has been extended?
In that case  you must go to a DMV office with your updated paperwork from the United States Department of Homeland Security DHS. We will update our records to show that your Temporary Visitor status has been extended so you can renew your license. Your new license will have your new temporary visitor expiration date.
Will do. But let me clear one thing up: so, as long as my foreign drivers license isn't expired I can use it to drive in NY?
Correct. Your valid foreign driver license allows you to drive without a supervising driver.
