Shure no problem. Well I never realy did any paper work for that except when the car is going on the ship. I always say that Im on vacation and will be around 3 months but they dont ask anything about the car. And I don't know how long you can actually have the car here. In Europe we have technical controls every few years and if you would have a US car you'll have to covert the headlights, tail lights etc. But I think if you want to keep the car in US it wont be problem, because it will pass the smog test and maybe change the DOT Lightning so you have side reflectors, but than you can change it back and the police wont say anything. What kind of car are you are you trying to import?
