If you are a first-time residency applicant and have a firma/certificado digital (electronic signature/certificate) you can now submit your residency documents electronically, rather than having to go in person to the extranjeria (foreigners’ office).
It can be quite a confusing concept for those who haven’t had one before, but it means that you can do your tax return online, consult your “vida laboral” and do various other administrative processes electronically. You can find out how to get your digital certificate and the benefits of having one on the button below, or consult your gestor.
