I would say if you can find you can do it in the UK then do, but...
Weather is a pain and will slow you down
Maybe think about europe rather than the states, no paper work, better weather, more focused on intense training, closer to home and our regs.
If you go away (and I did in the end) expect to do some back in the uk training to get used to the differences.
UK does seem to be mostly more expensive but not always.
Also I found going away removed all the day to day home life interruptions and side tracks.
and lastly for everyone that says they frown on students who switch there is another who says it'd not that important.
I think I'd be careful if your handing over bulk cash to anyone in the current situation.
be good to hear who you go with, why and how it goes.
best of luck
