I am from India and I came to Spain for business meetings. My plan was to stay for one month [but found out the business will be closed for one week for Christmas]. My visa is valid from 2nd December 2016 to 15 January 2017; the duration of stay is 30 days. I arrived in Barcelona on the 4th of December, per the visa, and I planned to leave by the 4th of January. I want to extend the stay until the 14th of January.
How do I apply for a visa extension? Is it actually necessary to apply for an extension since I am leaving before the expiry date on the visa (15 January)?
