I have included some links to some blogs that I find very interesting:

http://immigration-duckblogger.blogspot.com/:
This blog, written by DuckBlogger is also about immigration and immigration reform in the United States. This blog is fantastic because of the abundance of information available on it. The posts are well written and have excellent sources cited. I enjoy reading this blog not only because it's on a subject I'm very familiar with but also because it's so well-informed. He starts off with very basic information on immigration before branching out into more complex aspects of it.

Written by Kia, this blog about Middle East Politics in 2008 not only has excellent information, but also has a unique perspective. The author grew up in Iran and offers a more personal perspective on the happenings in the Middle East. It's a really great blog if you want personal stories behind the abundance of information he also provides. Also includes a nice video bar for more information.
