Someone asked about the Missouri Law the other day re: AZ law Here it is.

            2. No municipality shall enact or adopt any sanctuary policy. Any municipality that enacts or adopts a sanctuary policy shall be ineligible for any moneys provided through grants administered by any state agency or department until the sanctuary policy is repealed or is no longer in effect. Upon the complaint of any state resident regarding a specific government entity, agency, or political subdivision of this state or prior to the provision of funds or awarding of any grants to a government entity, agency, or political subdivision of this state, any member of the general assembly may request that the attorney general of the state of Missouri issue an opinion stating whether the government entity, agency, or political subdivision has current policies in contravention of this section.

            3. The governing body, sheriff, or chief of police of each municipality shall provide each law enforcement officer with written notice of their duty to cooperate with state and federal agencies and officials on matters pertaining to enforcement of state and federal laws governing immigration.

            4. This section shall become effective on January 1, 2009.

            208.009. 1. No alien unlawfully present in the United States shall receive any state or local public benefit, except for state or local public benefits that may be offered under 8 U.S.C. 1621(b). Nothing in this section shall be construed to prohibit the rendering of emergency medical care, prenatal care, services offering alternatives to abortion, emergency assistance, or legal assistance to any person.

            2. As used in this section, "public benefit" means any grant, contract, or loan provided by an agency of state or local government; or any retirement, welfare, health, postsecondary education, state grants and scholarships, disability, housing, or food assistance benefit under which payments, assistance, credits, or reduced rates or fees are provided. The term "public benefit" shall not include unemployment benefits payable under chapter 288, RSMo. The unemployment compensation program shall verify the lawful presence of an alien for the purpose of determining eligibility for benefits in accordance with its own procedures.

            3. In addition to providing proof of other eligibility requirements, at the time of application for any state or local public benefit, an applicant who is eighteen years of age or older shall provide affirmative proof that the applicant is a citizen or a permanent resident of the United States or is lawfully present in the United States, provided, however, that in the case of state grants and scholarships, such proof shall be provided before the applicant receives any state grant or scholarship. Such affirmative proof shall include documentary evidence recognized by the department of revenue when processing an application for a driver's license, a Missouri driver's license, as well as any document issued by the federal government that confirms an alien's lawful presence in the United States. In processing applications for public benefits, an employee of an agency of state or local government shall not inquire about the legal status of a custodial parent or guardian applying for a public benefit on behalf of his or her dependent child who is a citizen or permanent resident of the United States.

            4. An applicant who cannot provide the proof required under this section at the time of application may alternatively sign an affidavit under oath, attesting to either United States citizenship or classification by the United States as an alien lawfully admitted for permanent residence, in order to receive temporary benefits or a temporary identification document as provided in this section. The affidavit shall be on or consistent with forms prepared by the state or local government agency administering the state or local public benefits and shall include the applicant's Social Security number or any applicable federal identification number and an explanation of the penalties under state law for obtaining public assistance benefits fraudulently.

5. An applicant who has provided the sworn affidavit required under subsection 4 of this section is eligible to receive temporary public benefits as follows:

            (1) For ninety days or until such time that it is determined that the applicant is not lawfully present in the United States, whichever is earlier; or

            (2) Indefinitely if the applicant provides a copy of a completed application for a birth certificate that is pending in Missouri or some other state. An extension granted under this subsection shall terminate upon the applicant's receipt of a birth certificate or a determination that a birth certificate does not exist because the applicant is not a United States citizen.

            6. An applicant who is an alien shall not receive any state or local public benefit unless the alien's lawful presence in the United States is first verified by the federal government. State and local agencies administering public benefits in this state shall cooperate with the United States Department of Homeland Security in achieving verification of an alien's lawful presence in the United States in furtherance of this section. The system utilized may include the Systematic Alien Verification for Entitlements Program operated by the United States Department of Homeland Security.

            7. The provisions of this section shall not be construed to require any nonprofit organization organized under the Internal Revenue Code to enforce the provisions of this section, nor does it prohibit such an organization from providing aid.

            8. Any agency that administers public benefits shall provide assistance in obtaining appropriate documentation to persons applying for public benefits who sign the affidavit required by subsection 4 of this section stating they are eligible for such benefits but lack the documents required under subsection 3 of this section.

 28.824. All law enforcement officers shall inquire into the citizenship andimmigration status of any person under arrest for a violation of any state law or municipal ordinance, regardless of the person's national origin, ethnicity, or race. In all such cases where a person indicates that he or she is not a citizen or national of the United States, the law enforcement agent shall verify with the federal government whether the alien is lawfully or unlawfully present in the United States, under 8 U.S.C. 1373(c). If the alien is verified to be unlawfully present in the United States, the law enforcement officer shall cooperate with any request by federal immigration authorities to detain the alien or transfer the alien to the custody of the federal government."

There are also penalties applied to businesses that knowingly hire illegal aliens.

 Missouri also bans in-state tuition aid for illegal aliens at state junior colleges.
