An E-Verify Third Party Agent is a liaison between E-Verify and employers wishing to participate, but who choose to outsource submission of employment eligibility verification queries for newly hired employees. E-Verify Third Party Agents conduct the verification process for other employers/clients. An E-Verify Third Party Agent must register on-line and sign an MOU with SSA and USCIS. Once the MOU is approved, the E-Verify Third Party Agent can then begin registering employers/clients who have designated it to perform the company's verification services. Each employer/client will also be required to sign an MOU and will have a unique E-Verify client number.
