Getting a German work visa depends on your citizenship or nationality. While certain countries are exempt from the need to get a visa, the process is different for some countries. You must satisfy certain conditions to apply for a German work visa.
Recognition of your qualifications by German authorities:
When applying for jobs in Germany, you must not only provide proof of your professional and educational qualifications but also acknowledge your professional abilities by German authorities. This is especially important for professions such as physicians, nurses, and teachers.
Knowledge of German:
You will have an advantage over other job searchers if you have some knowledge of the language. If you have the relevant educational credentials, work experience, and a basic understanding of German, you will have an excellent chance of finding work here (B2 or C1 levels). However, knowledge of German is not essential for professional vocations such as research and development.
