Creates new provisions relating to illegal immigrants

SB 1321 creates a new Missouri state offense for people entering the state while violating federal immigration law (8 U.S.C. § 1325). It imposes a $10,000 fine for a first offense (classified as a misdemeanor) and escalates to a class E felony for repeat violations. The bill mandates court-ordered removal from Missouri after fines or prison terms, requiring specific details like transportation to a port of entry and law enforcement monitoring. Law enforcement officers may arrest individuals suspected of violating this provision upon probable cause. This bill directly affects immigrants entering Missouri in violation of federal immigration rules, establishing state-level penalties distinct from federal enforcement.
