Senate Bill 484 aims to prohibit the use of state and local facilities for the detention of individuals based solely on their immigration status. The bill specifies that no state agency, political subdivision, or county sheriff may allow the federal government to use their facilities for such detentions. Additionally, it prohibits these entities from expending funds to establish or operate immigrant detention facilities within Wisconsin.

The bill introduces a new section, 20.935, into the statutes, which outlines definitions and the prohibitions regarding detention and funding for immigrant facilities. It clearly defines "political subdivision" and "state agency" and emphasizes that any detention based solely on immigration status is not permitted in state or local facilities. Furthermore, it reinforces the prohibition on financial support for the establishment or operation of immigrant detention facilities in the state.
