In a letter sent on Thursday to the committee, Marc Apter, president of IEEE-USA. voiced opposition to the Hatch proposals.
"Every part of this package has the same purpose -- to make it easier for employers to fire Americans and replace them with temporary foreign workers," wrote Apter of Hatch's amendments.
The IEEE-USA, a professional group for engineers, has opposed expanding the H-1B program, but supports permanent residency for STEM graduates.
The committee recessed early Thursday afternoon and will resume negotiations on its amendments on Monday.
