On March 1, 2003, the Immigration and Naturalization Service became part of the U.S. Department of Homeland Security and its functions were divided into various bureaus of that department. There's the Bureau of Citizenship and Immigration Services. Services mind you. And there's the U.S. Immigration and Customs Enforcement (ICE). But underneath the new coat of paint, it's still the same loathsome and arbitrary bureaucracy. Read those two links and gnash your teeth.
Or maybe (here's a horrible thought), now that it's got that Homeland Security vibe, it's getting worse.
