"Immigration and Emmigration" (nytimes.com)

http://topics.nytimes.com/top/reference/timestopics/subjects/i/immigration_and_refugees/index.html?scp=1-spot&sq=immigration&st=cse

This article talks about how the United States has always had immigration, but since the beginning of the 21st century, we have had more immigrants since the 1920's. It also adds that by 2008 the U.S. had about 11.9 million illegal immigrants living here. President Bush and Obama have tried to fix this problem with ideas like bipartism bill, and a "truly civil detention system." These ideas so far have not worked but the country is still trying to make it easier for immigrants to immigrate legally.
