When I finished my master's studies in Germany, I got what I think was a job seeker visa (my permit said "16 Abs. 5"). After that, I got a Blue Card (some 13 months ago). My current contract is expiring in a few months (therefore, my Blue Card too) and I haven't found a new job. Can I apply again for a Job Seeker Visa or do I need to return to my home country after my Blue Card expires?
