If you have a British passport then post-Brexit, Ireland is one of the easier countries to move to as you don't need a visa or work permit as I understand it.I'm a civil engineer but working in a senior role in vertical construction. My wife works as PM for NZs largest Telco company. It's safe to say that we have it extremely sweet. We're looking at serious drops in income if we move back to the UK. I genuinely cannot believe the rubbish money on offer.
We're also looking at Dublin as the salaries in our fields on offer is higher, but they seem to have a housing shortage/crisis from what I read. Then there's the passport/visa thing. Not sure what the deal is for UK passport holders (and now NZ passport holders) these days with moving to Ireland.
For most countries UK citizens now need a visa and/or some other form of work permit, and as most of those are granted only with a secure job offer, that makes emigration a pipe dream for many, since you will only get a job if a) there is no applicant from that country suitable b) no other EU applicant suitable or c) you have some niche skill that is in high demand.
I really do feel for anyone trying to emigrate from the UK post Brexit, but Ireland is a notable exception.
