There are a couple of schools with Dual EASA/fAA instructors , i think they can BFR's but not skills tests for new licences .
Try Atlantic helicopters in Leeds .
To do FAA licences you need to go through all the bull**** of finger prints , TSA checks , etc
So in all fairness , I doubt it ....
Your better off just getting your 355 /IR renewed , get your 135 rating done
Contact Atlantic , they can do FAA licences in Leeds I think
