What is MERCURIO
and why it matters

No. You can also apply in person at the Delegación del Gobierno with an appointment (cita previa). The outcome is the same. However, appointments are very hard to get, especially in large cities. MERCURIO is the legal way to submit without queuing at any time.

Yes, in the «Acceso en representación» mode. The representative acts under a power of attorney (apoderamiento): apud acta or notarial. The link between you and the representative must be registered in Apoder@ or with the Consejo General del Notariado. How to grant it: how to grant authority to file.

Check the status on Infoext2 («Información sobre el estado de expediente / solicitud de extranjería»): sign in with Cl@ve or use the form, which asks for the submission form identifier, the submission date, the nationality and the applicant's year of birth. The «Consultar el estado» option inside Mercurio shows the expediente number of a new application. If you choose electronic notification, check your inbox regularly: a notification left unopened is treated as rejected after ten calendar days, the deadline to reply to a requerimiento keeps running anyway, and the case may be archived.

You can submit on paper in person, or through a representative: they file in the «en representación» mode if they hold a power of attorney (apud acta or notarial) registered in Apoder@ or with the Consejo General del Notariado. Message us on WhatsApp — we will review your situation.
