Hoping Steve will chime in here, but it would seem to me that DPS cannot just make unilateral decisions like this on their own. There needs to be more to it than their just "telling people that's the way it is now."
This does involve rules and laws. Those can't "just" be changed on a whim. I'm calling BS for now.
Verbal discussions with DPS do not effect the law or administrative code. DPS personnel are welcome to tell anyone anything they wish and though it is irresponsible of them, in their position, to misrepresent the law and administrative code - their verbal discussions have no more force of law than what you read on the internet.
Fact: NM honors or has reciprocity with other states; authorized by NM Statute 29-19-12.
Fact: Guidelines for reciprocity/honors are outlined in NMAC 10.8.2.29
Fact: There are no other requirements or exclusions in NM Statue or NMAC regarding reciprocity/honors
Fact: NM DPS does have authority to determine what states are recognized and is required to post those state on their site
Fact: NM DPS cannot alter the NMAC without a promulgation hearing and has no authority over the Statute.
Fact: There is no requirement for a licensee of another state to hold a NM license, regardless of residency.
Anything else you may have heard other than what you read in the law and administrative code is simply not accurate.
