The memorandum of understanding (MOU) is the legal document describing the agreement between the Department of Homeland Security and the entity requesting participation in E-Verify. It is a simple statement of shared and agreed upon responsibilities for participation in this government program. Before successfully enrolling in E-Verify, employers and employer agents must agree to the terms of the MOU and electronically sign the document. The document will then be electronically signed by the Department of Homeland Security. Employers and employer agents should print a copy of the MOU for their records. In addition, the client of an employer agent will need to sign an MOU.
