Had a fun morning.
Didn't notice the address on the letter but went to the Auslanderamt office I had just been to a couple of months ago.
Saw a sign in the locked door into the place that just stated it had moved. Mentioned a new number on the same street ( numbers not being exactly a big thing in downtown Germany ). The first thing I thought was how helpful it would have been if they just had an arrow pointing in the direction of the new office.
Walked right past it as the office was in a new building that looked still under contruction. Came back to the building and went up an elevator to the second floor as stated in the building directory. When I got to the 2nd floor, all of the doors were locked and there was a sign indicating that you must enter the Auslanderamt through the buildings back door ( back down the elevator, out of the building and into an entrance in the building's back alley )!
I found it all quite amusing, especially knowing it was my last visit to the Auslanderamt for a long time. But I can just imagine how some poor soul from Pakistan or Africa must feel when he is directed to the back alley - not fit to come into the front door of the office building with the non-auslanders!
I really wonder how much of the treatment of poor auslanders is just some kind of oversight or rather somebody in the planning department is really showing contempt for those that wish to settle in this country!
