States often institute residency requirements in order to prevent migration of uninsured persons from neighboring states. Programs employing residency requirements will usually require enrollees to be a resident of the state for some specified minimum period.
- MinnesotaCare requires enrollees to have established residency for a minimum of six months before becoming eligible for MinnesotaCare. This applies only to adults without children. The Medicaid criteria apply to families with children.
- Other states use residency requirements to prevent (or allow) illegal immigrant children to access their state program.
- Washington requires applicants to reside in the state and have United States citizenship.
- The CaliforniaKids program requires applicants to reside within the state, but it does not require enrollees to have already established legal residency in the United States.
