Our explanation

Choosing the wrong route

A common mistake is starting EU citizen registration certificate when another authorisation fits better, leading to inadmissibility after months of waiting. Compare social, labour and family roots, or visa versus modification, before paying fees. The free orientation test may narrow options but does not replace legal checks. Check certificate expiry and consistency between passport, empadronamiento and Social Security. Keep stamped copies and registration receipts with date and file number. If you receive a formal request, reply within the deadline stated in the notification.

Incomplete or inconsistent documents

Partial certificates, non-sworn translations or simple instead of historical empadronamiento trigger chain requests. Passport entry and exit dates must match municipal certificates. Do not hide irregular periods if the procedure requires transparent stay history. Check certificate expiry and consistency between passport, empadronamiento and Social Security. Keep stamped copies and registration receipts with date and file number. If you receive a formal request, reply within the deadline stated in the notification.
