CHICAGO – Chicago Mayor Rahm Emanuel has proposed what he calls an immigrant-friendly ordinance that beefs up existing practices by adding protections for illegal immigrants.

It says Chicagoans who are illegal immigrants will only be detained if they're wanted on a warrant by local or federal authorities or if they've been convicted of a serious crime.

For decades, city agencies haven't been allowed to ask the immigration status of people who want services; police also haven't been allowed to question victims or witnesses about legal status.
