@WayOutWestMom is much more of an expert than I am when it comes to UNM, but here’s what the AO told me back in mid-June.
He didn’t mention a limit on the number of NMFs. Doesn’t mean there isn’t one, of course, but the scholarship is automatic. They don’t get that many of them, around 15 or so, so I’m guessing that it’s not like OU where there are more than 150 and it’s a significant line item in the overall budget.
The AO said that the Amigo is automatic until funding runs out, and as of mid-June when we spoke, he was still awarding Amigos for fall semester.
There are other OOS tuition waivers for those whose scores don’t hit the mark for the Amigo. I know this is different than the above, so possibly I was given incorrect info but that whet he told me.
