CHICAGO (AP) — When Illinois' top political leaders touted a proposal to allow illegal immigrants to obtain driver's licenses, it was painted as public safety measure and had the backing of immigrant rights advocates, who deemed it a positive step in the fight for immigration reform.

But the idea has run into some resistance among illegal immigrants themselves.

For many of Illinois' estimated 250,000 undocumented residents of driving age, volunteering an address, photograph and birth certificate to a state database seems like a risk, possibly more than driving without a license.
