Statutory law In April 2010, Arizona enacted SB 1070, a law that would require law-enforcement officers to verify the citizenship of individuals they stop if they have reasonable suspicion that they may be in the United States illegally. The law states that "Any person who is arrested shall have the person's immigration status determined before the person is released". United States federal law requires that all immigrants who remain in the United States for more than 30 days register with the U.S. government. In addition, all immigrants age 18 and over are required to have their registration documents with them at all times. Arizona made it a misdemeanor crime for an illegal immigrant 14 years of age and older to be found without carrying these documents at all times. According to SB 1070, law-enforcement officials may not consider "race, color, or national origin" in the enforcement of the law, except under the circumstances allowed under the United States and Arizona constitutions. In June 2012, the majority of SB 1070 was struck down by the United States Supreme Court, while the provision allowing for an immigration check on detained persons was upheld. Some states contain "stop and identify" laws that allow officers to detain suspected persons and ask for identification, and if there is a failure to provide identification punitive measures can be taken by the officer. As of 2017, there are 24 states that have "stop and identify" statues; however, the criminal punishments and requirements to produce identification vary from state to state. Utah HB 497 requires residents to carry relevant identification at all times in order to prove resident status or immigration status; even so, police may still dismiss provided documents under suspicion of falsification and arrest or detain suspects. In early 2001, a bill was introduced to Congress named "End Racial Profiling Act of 2001" but lost support in the wake of the September 11 attacks. The bill was re-introduced
