What state will be be located in?
Some states, like New York, will give you a NY Drivers License based on you Canadian Province license.
Other states, like California, will require you to write the written test, then do a road test to obtain your California drivers license.
As for importing a vehicle, my moving company (paid for by my employer) said it is usually better to sell you car in Canada and buy a new/used car in US. Both the US and Canadian governments make it difficult/expensive to import a vehicle.
In my situation, my spouse and I decided to sell our Canadian vehicles before we moved. One was over 10 years old, so easy decision, the other was eight years old, we wanted to keep it, but decided to sell it in Canada. We moved to Southern California and my employer provide relocation assistance, which included a move and a 60 day rental car. It took me almost 60 days to obtain a California Drivers license in 2015. I had to make an appointment at DMV to do the written test, then after passing, make an appointment to do the drivers test. DMV is very slow!
The other concern is obtaining car insurance in US. Some US companies consider you a "new" driver, so higher rates.
We used Geico, they will use your Canadian driving history in consideration, to give you a quote, when you provide your Canadian drivers license number.
In our case, my spouse had a speeding ticket in the last three years in Ontario and they saw it in their system. We did shop around and Geico gave us the best auto insurance rates. (but insurance was more expensive in US versus Canada).
Good luck!
