When you move from one state to another state, that is definitely the case. I would have had to just take a written test and then would have received my license. International individuals are almost always required to take the full driving test simply because driving is so different in other countries and a lot of stuff doesn't apply to the US. I too learned in the UK, and when I moved to the US I still took driving lessons for a few weeks before taking the test because driving on US roads is dramatically different from the UK and there is a lot of little nuances to get used to.
