The next step in the process is to present yourself at the local immigration office for a face-to-face meeting. It's necessary to keep in mind that all procedures are fully automated. Hence, the immigration officials will not require any additional documentation than what you already have supplied. This means that your name, contact info, and arrival date are all enough to meet you for your basic Schengen visa requirements. Should you just happen to have any double citizenship (GERD & US citizenship), then you will also have to apply for a German work visa.
