I am in Austria on a Visa D multiple entry, which expires next month. I am a Philippine passport holder, and was in Canada when I applied for the visa. I have not yet completed my German course and want to remain in the country to continue it.
Am I able to extend the Visa D while I'm here in Austria? Or do I have to leave Austria and make an application from the Philippines? I just ask this since I am here already in Austria and I don't want to go back to my home country just to apply again for a new visa. It's not practical.
