Congressional Budget Office Cost Estimate: H.R. 2131: Supplying Knowledge-based Immigrants and Lifting Levels of STEM Visas Act (SKILLS Visa Act) [open pdf - 62KB]
"H.R. 2131 would amend immigration laws to increase the number of highly skilled noncitizens who could receive employment-based immigrant (permanent) and nonimmigrant (temporary) visas to live and work in the United States. In addition, H.R. 2131 would change the numbers of family-based immigrant visas available to certain categories of noncitizens. The bill also would eliminate the immigrant visas made available through the Diversity Visa program. On net, CBO [Congressional Budget Office] estimates that enacting H.R. 2131 would increase the U.S. population by nearly 1 million in 2024 and in 2034."
