In 1965, Congress voted to change the laws that had restricted immigration into the United States for more than four decades. The Immigration Act of 1965 resulted in a wave of increased immigration that continues today. How do recent immigrant groups compare with those of the last great wave of immigration a century ago? Are they successfully integrating into American culture or threatening America's cultural stability? Should immigration once again be restricted, or should we concern ourselves with helping immigrants assimilate when they arrive?
