Why wouldn't the states follow the federal government in their determination of applicant's immigration status? The USCIS clearly states that the PR status does not expire even if the GC expires. What is so hard to understand about this?
The state can argue that a PR can abandon his PR status,
have his PR status revoked due to lack of residence, or get deported.
Actually this is perhaps what the USCIS think too otherwise why do they
give GC with expiration date on it? Remmeber in old days a GC was valid
forever
