I am an Indian undergraduate student in my 4th year. I have been accepted for an internship in a German University. I applied for a short term Schengen visa (Guest Scientist / Visiting Scholar) at the German Embassy in New Delhi.I received a call from German Embassy a few days later asking for a ZAV certificate. My Prof. stays very busy. It would be helpful to know more about the ZAV and its application procedure.
What do I need to do to get a ZAV certificate from Germany?
