An immigrant-rights group has released a report (PDF) predicting that 25 states may try next year to pass anti-illegal-immigration laws similar to Arizona’s controversial legislation.

The number of states considering legislation modeled after SB1070, the bill that Arizona GOP Gov. Jan Brewer signed into law this spring, is apparently growing: Earlier, pro-enforcement groups said 22 states were considering the bill, the Washington Independent’s Elise Foley notes.

The new efforts are going forward even after a federal judge ruled key parts of the Arizona law unconstitutional and enjoined its enforcement in Arizona in July. That decision is now under appeal before the Ninth U.S. Circuit Court.

Georgia, Mississippi, Oklahoma and South Carolina are most likely to pass a similar law next year, the new report says. Tennessee, Utah, Florida, Nebraska, Pennsylvania, Texas, Arkansas, Indiana, Colorado, Virginia, Minnesota, Missouri, Idaho and Kansas made the report’s “maybe” list. In Maryland, Nevada, Massachusetts, North Carolina, Michigan, Ohio and Rhode Island, the legislation is seen as less likely to pass.

The report notes that from 2006 to 2008, municipalities passed a host of local laws and statutes cracking down on employers hiring illegal immigrants.
