A bipartisan group of influential lawmakers has urged US President Donald Trump to stop the abuse of H-1B and L-1 visas by outsourcing firms to replace American workers with cheap foreign labour. In a letter dated July 27, which was released on Tuesday, the group said a legislation introduced by them close these loopholes and overhaul these visa programmes to protect American workers and crack down on outsourcing companies which deprive qualified Americans of high-skill jobs. “We write because, for far too long, the H-1B visa has been abused by some corporations as a way to displace American workers with cheap foreign labour. We urge you to use your authority as president to the greatest extent possible to stop H-1B abuses, but we believe reform also must happen legislatively because of loopholes in the law,” the lawmakers said in the letter to the president.
