This letter, available here, clarifies when counties should send the MC 13 for immigration status. Applicants who claims to be citizens/nationals or have adequate immigration status on their applications will be run through the federal data hub in CalHEERS. If status can be verified this way, the MC 13 is not necessary, and the county can grant full-scope benefits. If status cannot be verified through the hub, applicants will be provided a 90-day reasonable opportunity period to resolve the matter before having benefits reduced.
