You can drive in New York State with a valid driver license from another country. As title says, can I exchange my Irish driving license for a US one as an Immigrant?Or do I need to go through the whole process? Inform them that you need a letter of entitlement to transfer your New York license to an Irish license. No one "converts" a license. You may qualify for a new license in some states, but you need to find out what each state requires.
