The Center for Immigration Studies (CIS) has created two interactive maps of H-1B dependent employers and H-1B employers who have been debarred or declared a willful violator. CIS created the maps using data from the Department of Labor.

There is a growing trend of employers using the H-1B visa to replace American workers with cheaper foreign labor and companies such as Disney and Abbott Laboratories also forced their American employees to train their foreign replacements in order to receive their severance package.

The first map displays the location of the over 2,000 employers who have been identified as H-1B dependent. H-1B dependent employers are defined as: an employer with 25 full-time workers or fewer, with eight or more of them H-1Bs; with 26-50 workers, there are 13 or more H-1Bs; and with 51 or more there are 15 percent or more H-1Bs.

The last map displays the locations and employers who have violated H-1B laws and who have been debarred from H-1B program for a period of time.

These maps were created from information supplied by the employers to the Dept. of Labor so there are errors. A 2011 study by the U.S. Government Accountability Office exposed how the H-1B visa was being exploited and showed that there was very little oversight of the program. According to the report the government doesn't even know how many workers are actually in the U.S. on H-1B visas at any given time.
