US SB3891

Establishes the Commission for Independent Monitoring of Immigration Enforcement as an independent body within the legislative branch to oversee ICE, CBP, and other immigration enforcement agencies for compliance with civil rights and civil liberties requirements.

Commission consists of 4 monitors appointed by Congressional leadership (with bipartisan consent) serving 5-year terms, compensated at Executive Schedule Level I, with an Executive Director hired jointly by the monitors.

Grants the Commission authority to conduct unannounced on-site visits, observe enforcement operations, access all DHS records and facilities, issue subpoenas (by 3-of-4 vote), and bring civil actions in U.S. District Court for the District of Columbia.

Requires monthly public reports to Congress, a public website for complaints and enforcement data, and allows the Commission to issue formal violation findings, refer potential criminal conduct to DOJ or state attorneys general, and impose penalties of $500,000 per day for serious or willful violations.

Terminates no earlier than 4 years after enactment, and only after 3 of 4 monitors determine all immigration agencies have been in substantial compliance with applicable requirements for at least 1 year.
