dcblogs writes: A top White House official told House lawmakers this week that the replacement of U.S. workers by H-1B visa holders is 'troubling' and not supposed to happen. That answer came in response to a question from U.S. Rep. Jerrold Nadler (D-N.Y.) that referenced Disney workers who had to train their temporary visa holding replacements (the layoffs were later canceled. Jeh Johnson, the secretary of the U.S. Department of Homeland Security, said if H-1B workers are being used to replace U.S. workers, then "it's a very serious failing of the H-1B program." But Johnson also told lawmakers that they may not be able to stop it, based on current law. Ron Hira, an associate professor of public policy at Howard University who has testified before Congress multiple times on H-1B visa use, sees that as a "bizarre interpretation" of the law.
