First of all, you need to check on what the insurance requirements are in the state in which you are resident in the US. Each state has its own requirements, but you may want to consider something more than the bare minimum policy. You may want to consider talking to an "independent agent" i.e. an insurance agent who represents a wide array of companies. But first of all you need to look into getting a local license asap. Many states only allow you 30 days or so from arrival to get a local license.

 

As Bev posted - you need to check DMV requirements for your US state. Driving for one year with a non US license applies to tourists only! One you have your license see an insurance broker. Google is your friend. Do not use on line options.

 

Don't know of any 'new driver' specialists, but some new drivers to the US have used their No claims eligibility to try and reduce premiums.

 

I got some quotes from Progressive, there is a premium on a foreign license but they don't seem to have an issue. The basic offering was cheap but equivalent to UK Third Party, making it more 'Comprehensive' was still comparable to what I pay in the UK for a midsize SUV of similar power.
