Importing to the US is straightforward and has been successfully done by a growing number of people on the forum now, so you should have no issues with customs or DOT once paperwork is done correctly. Also, Listerbell are quite familiar with what needs to be done their end to ensure proper paperwork, etc.
Registering for road use is a different story because every state has their own rules. The good news is that, as far as I know, it is possible in every state, you just need to look at your local DMV requirements. We can thank the hotrod crowd (SEMA) for pushing legislation on a state by state basis for this. See here:

Process seems pretty straightforward, the only part that caught my eye is that you need to pass your annual state safety inspection, so you'd better look up what that entails. I had to do the California safety inspection, but it was a bit of a joke - tested that the brakes can stop the car from 25mph in 25ft, checked that all the lights worked and were aligned, and the horn was working.
