I am an American student in the United States who is planning to travel to Germany this summer for a month and a half. I will be working there.
According to Article 14 in the employment ordinance , "(2) No consent shall be required for the granting of a residence permit to students and pupils from foreign universities and technical colleges for a period of up to 90 days during a period of twelve months, which has been mediated by the Federal Employment Agency."
Does this mean that I don't need a visa? I already have some sort of authorization from the German Federal Employment Agency. Is this enough?
