A new Colorado law intended to deny public services to undocumented immigrants appears to be causing widespread problems and accompanying irritation among Hispanic U.S. citizens and legal residents.

A group representing nurses who provide in-home medical services to non-ambulatory patients, meanwhile, said in a statement that the new legislation was "a big headache" because of both the requirement that patients' documents be reviewed and regulations covering the use of public funds. The law, Evidence of Lawful Presence: HB06S-1023, took effect Aug.
