Hi, and welcome to the forum.

As far as a straight transfer is concerned, I don't think that will work - unless some state has reciprocity with the UK. However, electrician qualifications are handled in the US on a state-by-state basis, so you need to take a look at what is required for a state license in the states you may be interested in. Google "state electrical licensing" and you should turn up LOTS of links to state licensing boards and information about qualifications, exams and whatever else you need.
Cheers,
Bev
