Missouri Immigration and Work Eligibility Laws

Overview of Work-Eligibility Compliance

If you’re hiring in Missouri, your first stop is the federal Immigration Reform and Control Act (IRCA)—which requires employers to verify each new hire’s identity and work authorization using Form I-9. Employers must retain this form for three years after hire or one year after termination, whichever comes later.

But Missouri adds a twist: E-Verify is mandatory for public employers and contractors doing business with state and local governments. Plus, there are added state-specific rules and penalties if you skip the verification steps.

Let’s walk through what Missouri employers need to know.

Immigration Reform and Control Act (IRCA) Compliance in Missouri

Does Missouri Law Differ From Federal IRCA?

Missouri generally aligns with federal IRCA standards but adds compliance enforcement through state statutes. While there are no alternative I-9 procedures or documentation rules, Missouri law penalizes businesses that knowingly hire unauthorized workers, particularly those contracting with public agencies.

No extra I-9 paperwork is required, but failure to comply with verification standards can impact your right to do business in the state.

Common Employer Questions About IRCA in Missouri

Which I-9 documents are most frequently rejected? The usual suspects—expired documents, incomplete forms, or wrong document combinations. Missouri doesn’t create its own list but expects full federal compliance.

Can we accept a digital driver’s license? Nope. Even if Missouri has a digital license option, federal law still requires physical, unexpired documents.

How soon must the I-9 be completed for remote hires? Section 1 must be done by the first day of employment, and Section 2 must be completed within three business days of that start date.

Are photocopies of documents permitted? Yes, but if you copy one person’s documents, you’ve got to do it for everyone—and store them securely.

Municipalities in Missouri With Additional IRCA-Related Requirements

Municipalities like St. Louis and Kansas City haven’t added their own I-9 rules. The state’s Missouri Revised Statutes § 285.530 prohibits local governments from enacting inconsistent regulations.

E-Verify Requirements in Missouri

Is E-Verify Mandated Beyond Federal Law?

Yes. All public employers in Missouri and any private business contracting with a state or local agency must:

• Enroll in E-Verify
• Use it to confirm the work eligibility of all new hires
• Maintain records to prove compliance

This has been the law since 2009, following the Missouri Employment Verification Law.

Common Employer Questions About E-Verify in Missouri

When must the E-Verify case be opened—hire date or start date? E-Verify cases must be opened within three business days of the employee’s start date.

What do we do with a “Tentative Non-Confirmation”? Provide the employee with a Further Action Notice, let them contest or not, and wait to resolve the issue before taking action.

How are remote workers handled? Use a designated agent to inspect documents and complete Section 2. Then E-Verify as usual.

Are there civil vs. criminal penalties for non-use? Yes. If you’re required to use E-Verify (e.g., you’re a state contractor) and don’t comply, you could face:

• Loss of business license or contract
• Civil fines

Local E-Verify Ordinances in Missouri

Missouri law prohibits local governments from passing their own immigration hiring laws. So you won’t find any extra E-Verify rules at the city or county level.

Visa & Employment Authorization Rules in Missouri

State-Specific Restrictions or Accommodations

Missouri doesn’t limit employment for visa holders but does require proof of lawful presence for various professional licenses—like:

• Medical and legal professionals
• Engineers
• Contractors and tradespeople

Missouri also participates in the Conrad 30 program to help underserved areas hire J-1 waiver physicians.

Common Employer Questions About Visa Sponsorship and EADs in Missouri

Can we file H-1B transfers for employees living out of state? Yes—Missouri has no restrictions on visa sponsorship that go beyond federal law.

Must we update payroll tax status when an EAD renews? Not at the state level, but yes for federal compliance—you must update the I-9.

Is there a state fee or notice requirement for foreign-worker layoffs? No. Missouri doesn’t require separate state notification. Federal WARN Act still applies for mass layoffs.

Municipal Ordinances Affecting Visa/EAD Employment Eligibility

None. Missouri’s uniform employment law policy prohibits local governments from enforcing their own rules.

Penalties for Non-Compliance in Missouri

Missouri takes a tough stance:

• Knowingly hiring unauthorized workers may result in revocation of business licenses
• Failure to use E-Verify if required can trigger contract termination or civil penalties

Federal penalties also apply:

• $281–$2,789 per I-9 paperwork violation
• Up to $27,894 per unauthorized worker knowingly hired

Record-Keeping & Retention Guidelines

No extra red tape here. Just stick with the federal rules:

• Retain I-9 forms for three years after hire or one year after termination, whichever comes later
• Keep E-Verify records in tandem with I-9s

Anti-Discrimination & Retaliation Protections

Missouri law mirrors federal anti-discrimination provisions under INA § 274B and adds enforcement through the Missouri Commission on Human Rights:

• No document abuse or unfair verification practices
• No retaliation for asserting employment eligibility rights
• No discrimination based on citizenship status or national origin
