Worksite Enforcement

_WorksiteEnforcement

Worksite enforcement is one aspect of overall immigration enforcement, focused on identifying the workers who are not authorized to work as well as the employers who knowingly hire unauthorized workers. As the research below discusses, worksite enforcement tools include workplace raids to apprehend unauthorized workers, the use of audits to examine identity and employment eligibility forms, and the levying of penalties against employers found to have violated the law.

E-Verify has been heralded as a key way to control unauthorized immigration to the United States, but federal efforts to expand the system stalled. There has been movement at the state level over the past decade, though, and there are signs it may rise in prominence again. This article details the history and challenges of E-Verify, and its limited uptake.

President Donald Trump signs an executive action

Within hours of his second inauguration, President Donald Trump moved to dramatically reshape U.S. immigration enforcement and policy. The changes set the stage for mass deportations, all but foreclose access to asylum at the border, and seek to create “shock and awe” that will reverberate around the country. This article examines the early-day policies, possible impacts, and likely headwinds.

Renewed U.S. state activism on immigration has echoes of the early 2010s, when Arizona’s SB 1070 defined a Republican-led push to increase enforcement that was ultimately muted by the courts and public backlash. Newer strategies rely on a novel array of tactics including migrant busing, litigation, and lawmaking. States are also moving in opposite directions, with some expanding rights for unauthorized immigrants, as this article details.

While Donald Trump’s presidency is perceived as being the most active on immigration, touching nearly every aspect of the U.S. immigration system, President Joe Biden’s administration has far outpaced his predecessor in the number of executive actions taken during his first year in office—even as the pace of change has gone largely unnoticed, as this article explores.

U.S. immigration arrests have declined to the lowest level in years.

This discussion, featuring California's Labor Commissioner and the head of the Tennessee Bureau of Workers' Compensation, launched a report that examines state innovations in labor standards enforcement in low-wage, immigrant-dense industries. With wage underpayment, payroll fraud, and other violations widespread in industries such as construction and car-washing, the discussion focused on how targeted enforcement can deter practices that hurt native-born and immigrant workers alike, cost state tax revenue, and disadvantage law-abiding employers.

The Carter presidency illustrates the long history of authorities that remain in use today, including parole and creation of lawful pathways to admit people in orderly ways, and the persistent roots of issues such as spontaneous migration from the Caribbean.
