Migrants who come to the U.S. to find work are now being hired more quickly, at higher pay and under better working conditions than at any time in recent memory. In many cases, employers and economists say, migrant workers are being paid as well as their American counterparts.  

Job vacancies in the U.S. increased to 11 million at the end of December, according to the Labor Department. While the tightness appears to be easing in the white-collar job market, employers say finding hourly wage workers remains a challenge. Unemployment hit 3.4% in January, the lowest rate in 53 years. Many small businesses say they are unable to hire enough native-born and naturalized workers and are paying a premium for migrant workers.
