Trump signed an executive order on Monday expanding restrictions on several work visas until at least the end of this year, including the L-1 visa that allows companies to transfer employees from overseas offices and the H-1B program for workers in specialty occupations.

“Immigration has contributed immensely to America’s economic success, making it a global leader in tech, and also Google the company it is today,” Google CEO Sundar Pichai said on Twitter.

“Preventing high skilled professionals from entering the country and contributing to America’s economic recovery puts American’s global competitiveness at risk,” a company spokesperson said.

Jason Oxman, CEO of the Information Technology Industry Council, another technology trade group, said the administration’s plan will have a “dangerous impact on the economic recovery.”

“As U.S. companies get their employees back to work, immigrants working in the technology industry are vital to sustaining promising recovery trends, as well as supporting the United States’ ongoing response to Covid-19,” Oxman said.
