During the internal evaluation and approval process of your visa application (Cambio de calidad migratoria) or of the application for the extension of your visa, Migraciones may discover that you haven’t uploaded all required documents, that an uploaded document isn’t to their liking, or they want an additional document. You are then sent a notification informing you about it and asking you to submit the document in question.
Read the Migraciones notification carefully. Usually, you only get 5 (sometimes 10) days to upload the document. If you don’t react within the deadline, your application can be dismissed.
If you have the document, make a PDF of it (max size 3MB) and upload it on the Agencia Digital. How this so-called Subsanación is done, is explained in our article “Subsanacion – Submitting documents”.
If you don’t have the document yet and won’t be able to submit it within the deadline, you still have to react and can apply for an extension of time to hand in the document later. The process is called Solicitud de ampliación de plazos and can only be requested if you applied for a visa (Cambio de calidad migratoria) or for an extension of your visa.
As soon as you have submitted the request for an extension of the deadline, you have an additional 30 days to upload the document. Officially, you can only apply for the extension of the deadline one time, but a few of our readers informed us that Migraciones accepted a second extension of the deadline when they presented a valid reason (for example, waiting for the criminal background check with Apostille from abroad). However, be aware that if a second extension isn’t granted, Migraciones could dismiss your visa / visa extension application (which you then could appeal).
