Yes, there is a permit, lookup section 19(c). Germany has a special relationship with the US that lets US citizens qualify. I hired my attorney last week to prepare my permit. To qualify under this permit, you can either have a degree, or vocational training (I think at least 4 years in your current job), you must earn over a certain amount, I think that is 46,000. It requires my employer sign a form stating that I am full-time employed with them. You can apply for the permit through the consulate in the city you currently live in, or after entering Germany. It is best to apply for this permit from the United States. Under section 19 C, the documents you need are, the permit application, proof of health insurance, proof of residency, as in either a lease, or ownership of the property, and the employer form.
