All Spanish visas can be extended, except the Student Visa (up to 190 days). This type of Student Visa requires you to leave before the day of expiry and you cannot apply for a different kind of visa from within Spain if you have arrived on this particular visa.To renew your visa, give yourself plenty of time to allow for delays. We recommend starting the process at least two months in advance to avoid any unpleasant surprises. It is always better to be ready ahead of time than not.
Take all of the paperwork that you were asked for when you first applied for your visa to the Oficina de Extranjeros. This is the place all expats have to go to at some point, whether for obtaining the national identity card or filing paperwork for the visa extension.
Oficina de Extranjeros
Passeig de Joan Borbón, 32
Telephone: 93 2240610Once there you will be given the form you need to extend your stay.
The truth is that if you are completely prepared with all of your paperwork, the person behind the counter won´t even ask for it and your renewal will be rubber-stamped. If on the other hand you arrive unprepared, you are guaranteed to get the only administrative stickler in the building. Renewing your visa is relatively easy, as long as you put in the work beforehand and make sure you have all of the required paperwork on hand. However, as previously mentioned, it is a time-consuming process, so you should start in advance and allow for all kinds of delays when you are waiting at the main office.
