Illegal immigrants as tenants

[Philip Bennett]

I have an applicant for a property in Anchorage, Alaska that is wanting to sign a lease for a family member that is an illegal immigrant. The individual wanting to sign the lease is unable to provide a completed application for the would be adult tenant. I've never encountered this and don't really know if I can legally or even should rent to someone, knowing that an illegal immigrant will be residing in the property. Any advice!?
