Looking for information on treatment of Iranians in German “refugee camps”

I’m looking for research information on Iranian “refugee camps” in Germany in the past 10 years, so that my novel in progress has better background information. 

Looking for reports on living conditions, permits to work, government subsidies, boundaries for travel restrictions if any, etc. 

I also need to know the cities in Germany where Iranian “camps” were/are set up.  In particular, was/is there one just outside Frankfurt?  You may also “blog” me at my website: www.suspenseiskillingme.net on the blog page. 

I appreciate any help I can get.  I have an Iranian source, but his experience with the “camp” dates to the mid ’80’s and I need current data.  Only in English!
