Language assistants from member countries of the European Union: how to obtain the EU Registration Certificate .

The first step to take upon arriving is to apply for an EU Registration Certificate at the immigration office or police station in the assigned city or town. Assistants will have to go to the local immigration office (or, if there is none, to the corresponding police station), in order to apply for registration in the Central Register of Foreign Nationals.
To apply for the EU Registration Certificate, a fee must be paid (about ten euros) and the following documents will have to be provided:

Documents to be provided:

• Modelo oficial EX-18 (the EX-18 form), in duplicate, duly completed and signed. Valid identity document (if it is expired, a copy of both the expired
  document and the renewal application will have to be provided). The original document must be presented upon submitting the application.
• Appointment Letter.
• Proof of payment of the corresponding fee.

Once the application is submitted and the fee has been paid, a Registration Certificate will be issued, which will include name, nationality, address, date of registration and Foreigner Identification Number (NIE). This number will be required by the bank to open the Spanish bank account which will allow the assistant to receive the monthly stipend.

It may also be possible to request the NIE, before arriving in Spain, at the consular offices of the Embassy of Spain in the assistant’s country. However, once in Spain the assistant is required to apply for the EU Registration Certificate locally.
