If a contest were held to name the visas most hurtful to American workers among the 25-odd federally issued ones that include employment authorization, the likely outcome would be a tie. The overwhelming majority of employment-based visas mean that an American job will be lost to a foreign national or that a qualified U.S. candidate will be denied job opportunities because craven employers have such easy access to the cheap labor that visa holders provide.
Even visas that specifically deny employment are illegally and fraudulently substituted for work permits. Infosys Limited, an Indian outsourcing company, hired B-1 visa holders to perform skilled and unskilled labor that denied chances to Americans even though that visa is designated for temporary entry only. An estimated 1 million Indian nationals – predominantly lawful, white-collar IT workers – prevent American citizens from obtaining gainful employment.
