My experience is that these kind of Catch-22's between states cause those states enough embarrassing questions that they set up procedures to take care of folks caught in those catches. But those little-used procedures are unlikely to be found on their websites.

So here's what I would do. Call and tell whomever answers what the problem is. If that person says "Tough," whether nicely or not, then talk to that person's supervisor, and so on until you find the person who knows how they handle the problem -- which their government has already dealt with a large number of times.

If this doesn't work at the RI end (where it should), try the other end.

Should that fail, hook them together in a confernce call at the super-supervisor level and make them tell each other why they cannot make exceptions to allow reasonable people to do reasonable things.

Somewhere in here fits, maybe, the US Consitution's term "Full faith and credit," which applies to both states (neither of which has seceded yet -- though I believe RI seriously considered it once).

My guess is that RI has a way to provide you a title, and that you won't have to go very far into the bureaucracy before you get to the person in RI's DMV who knows how it is done.

Or listen to Ryan above, as he's BTDT. But call ahead to NV to make sure they have also BTDT.

Good luck.
