Visa for internship in Germany

Does anyone have experience obtaining a Visa (type D) to work in Germany as an intern? Due to Covid 19 restrictions there are limits on travel without a Visa unless you meet specific criteria. The visa process is pretty complicated and you have to appear in person to apply for the visa at a consulate. For my student, that a day’s drive to get there. Help from the college he attends is not an option. They will not provide support to students to travel abroad at this time.
