I'm from Germany and live close to Washington D.C. right now, where the German Embassy is located.
Is it a good place to go there to set up an appointment and talk to them?
-Or where else could I go to talk to?

I don't have the two year foreign residency requirement. I'm here since January this year and my visa will run out February 09. -Its a simple J-1 visa.
I would receive the two year foreign residency requirement if I extend my year as an Au Pair from this organization I am in (Cultural Care Au Pair).
Is there a way to apply for this J-1 waiver without contacting Cultural Care?
