Hello
Bit late
Stuttgarts buerograzy got online the last months. That helps.
You can download most forms and use the advanced PDF options to fill them out.

Now that site was in german the last time I checked it.
Finding a apartment or house in the Stuttgart area is tough and expensive.
You also can rent homes turnkey equiped like here:

The stuttgart area is used to americans, some 15 years ago we had over 10 000 US citizens around here. Stuttgart still has a large comumity ( EURCOM, AFN Radio ). I think the comunity still has a own shool, babtist curch and a PX ( wich is only for army guys ).
On the US sites you will find loads of informations about living in Stuttgart.

I think Porsche has a assesment (?) program like DC, Bosch and all the others who do most paperwork and stay on your side if you have questions or problems.
Also Porsche has allready several employes with US origin.
The internet service branch is in Ludwigsburg thats a bit cheaper and less crowded compared to the Stuttgart city pan.
