After studying in Germany, is there an 18 months stay back option for job search?

Yes, after completing your studies in Germany, you can apply for an 18-month Job Seeker Visa to stay and search for employment related to your degree.

During these 18 months, you may work in any job to support yourself while looking for a suitable position. If you secure a job matching your qualifications, you can switch to a work permit or the EU Blue Card for long-term employment and residency. This stay-back option is not renewable, so you must find a relevant job within the 18-month period.
