Require peace officer to check and report immigration status during lawful stop

This bill requires peace officers in Montana to check and report the immigration status of individuals during lawful stops, unless doing so would hinder an investigation. It directly affects law enforcement officers and individuals who are stopped by police under existing stop-and-frisk provisions. The key provision adds a new requirement for officers to make a reasonable attempt to determine immigration status when practicable and report non-citizens who are not lawfully present to federal immigration agencies. The bill amends existing Montana law to include this immigration status check as part of the standard investigative stop procedure.
