Unauthorized arrivals in the U.S. have reached their lowest levels since the early 1980s, according to a paper by the Center for Migration Studies. The paper, which assesses unauthorized immigration over the past two decades, shows that unauthorized arrivals increased to more than one million in 2000, then began to drop steadily. It calls for legislation that reforms the legal immigration system, legalizes a large percentage of the unauthorized, and effectively responds to nonimmigrant visa overstays.
