The United States has issued more than 1 Million new green cards every year since 2005 and in 8 of the past 10 years. That many new green cards, combined with non-immigrant work visas, adds 125,000 new workers to the job market every month who compete with unemployed Americans and recent high school and college graduates for jobs. High immigration levels increase competition in the job market and depressed wages.
The majority of illegal-alien workers and low-skilled immigrants hold jobs in service, construction, and manufacturing. But native-born Americans hold the majority of these jobs within each sector. The Pew Hispanic Center also estimates that only 4% of illegal workers in the United States work in agriculture. Seven million illegal aliens hold non-agricultural jobs in the U.S.
