Iowa Code § 222.65

If an application is made for placement of a person in a state resource center or special unit, the department’s administrator shall immediately investigate the residency of the person and proceed as follows:

1. If the administrator concurs with a certified determination as to residency of the person so that the person is deemed a state case under section 222.60, the administrator shall cause the person either to be transferred to a resource center or a special unit or to be transferred to the place of foreign residency.

2. If the administrator disputes a certified determination of residency, the administrator shall order the person transferred to a state resource center or a special unit until the dispute is resolved.

3. If the administrator disputes a certified determination of residency, the administrator shall utilize the procedure provided in section 331.394 to resolve the dispute. A determination of the person’s residency status made pursuant to section 331.394 is conclusive.
