An Arizona Congressman plans to introduce a bill to end a federal government program — widely used as a pathway to the H-1B visa — that lets foreign students and graduates of U.S. schools work in this country for up to three years. Republican Paul Gosar expects to introduce to the House of Representatives within two weeks the “Fairness for High-Skilled Americans Act of 2019” to kill the Optional Practical Training program, his office said Friday. The OPT program grew 400 percent in the decade after the government in 2008 boosted the amount of time students and graduates in science, technology and math fields could stay in the U.S.
