Is German language required for a German work visa?

German proficiency is not always mandatory to obtain a German work visa, but it depends on the type of job and employer requirements. For many positions in international companies, especially in IT, engineering, and research, English may be sufficient. However, for jobs involving direct interaction with German-speaking clients, patients, or customers—such as healthcare, education, or public service—German language skills are often essential. While the visa itself may not require proof of German proficiency in all cases, having a good command of the language significantly improves job prospects, integration, and long-term career growth in Germany.
