I am applying for a training-based Schengen visa. I have to go to Germany and work on a research project with a prof. for about 6–8 weeks. The prof. is providing me the accommodation at his home, a small isolated room.
The visa requires, "Proof of Accommodation", a "Training Approval letter", and a "Covering letter".
I wanted to know the exact format for these letters as per what the embassy looks for.
