The Maricopa County Attorney published what appears to be a manual for Arizona law enforcement officers about Arizona’s new immigration law, SB 1070. Federal law requires that every alien registered in the U.S. must be issued a certificate of alien registration card [8 USC Section 1304(d)] and carry the card at all times [8 USC Section 1304(e)].
Federal law also provides that every alien over 13 who stays in the US longer than 30 days is required to required to register [8 USC Section 1302(a)]and an alien who fails to register is guilty of a misdemeanor [8 USC Section 1306(a)].
