As a policewoman would say: Do you have your car registration, car insurance, and driver's license. Those are required. Some states also require a vehicle inspection and for the vehicle to pass an emissions test.
Right hand drive cars are legal in the US. Additional mirrors to compensate for the position of the steering wheel may be required, however.

Yes, but you need an exotic animal liscense/reptile liscense.
Exotic simply means 'not domestic' or 'from another country'. At some point, the word exotic gained an additional meaning...possibly because exotic race cars were winning more races than domestic cars or maybe because exotic actresses were seen as hotter than home-grown. It has come to mean higher quality, faster, sexier, and a lot of other comparatives. That has led at least one US car manufacturer (Chrysler) to run advertisements in the US claiming that their domestically built sports car is exotic.
