I really wonder how happy they are after spending couple of Bln's considering the London real estate market now.
If the English want to destroy themselves they're entitled to do so, but not drag the rest of us down with them.
So I fully understand the anger, if it weren't for the recent Scottish referendum that would be a different situation, but that did happen and for the Scots this must be extremely bitter right now.
Switzerland has an FMP agreement with the EU which is something that clearly the UK doesn't want hence the BrExit.
I'm still thinking about Amazon they are registered in Luxembourg over 40% of the items I order ship overnight from the mainland (France/Germany) a lot of things will have to change.
I do not believe the UK is going to crack down on tech engineers and phds that want to work in their country.
When the UK finally leaves then yes that could be how immigration is managed.
We won't make any rash decisions but I think my partner and me are going to leave medium term despite us having great and interesting jobs.
That's not a decision based on economics but on "soft" feelings.
You would have the extra friction of proving to the UK government that you are skilled. There would probably be a requirement for formal education, so self-taught programmers are in trouble.
I admit I am speaking in my own interest here, as a Swedish person living and working in the UK. When I got a job here I just packed up my stuff and moved. I showed my passport to the border machine and that was it.
If I needed a skilled worker visa, I would probably have had to pay a certified translator to translate my diploma, send in both translation and original, and hope they send them back. Do the same thing for a dozen other documents. The employer would need to submit something, which may be fine for Google but harder for a startup. Then wait for months, because the home office has no incentive to be quick.
I hope this is going to change now.
