Germany has a well-organized and efficient visa processing system. The country offers several visa options based on your country of origin. Those belonging to EU nations do not need a work visa or permit to work in Germany. Those from non-EU nations must apply for a work visa.
If you already have a job offer in Germany and are a graduate or post-graduate, you can apply for an EU Blue Card before moving to Germany. However, the easiest way to get a work visa in Germany is to apply for the Germany Jobseeker visa.
