The Real ID Act of 2005 requires all states to obtain specific identification documents and verify their authenticity before issuing driver's licenses and official state ID cards. It also prohibits states from accepting any foreign documents except a passport, and it requires states to verify that applicants are in the country legally. The project has been estimated to cost about $11 billion nationally.
States must begin implementing the new law by May 2008, and fully implement the program within five years.
