If you are an EU resident, in order to get your NIE you can make an appointment (cita previa) at the Oficina de Extranjeros online. As there is a limited number of appointments allocated every week, it can be quite challenging to get one. Our advice would be to search for an appointment from 8:30am every day until you are successful. You can also contact an agency to help you get your NIE quickly and efficiently.   It might be handy to brush up on your Spanish or to go with someone who speaks the language, just in case the person issuing you your NIE speaks limited English.
