I hope this question fits the site. I am Finnish, planning to do a PhD at the UK. Since Finland is part of the EU, is there any paperwork I would need to do in order to get to work at UK? The stay would be about 3-4 years, I guess. I would be moving with my family (wife and children).
As far as I understand, as a EU citizen (except for Croatia at the moment) you don't need any permits or other paperwork; in other words you have the exact same right to relocate and look for work and get employed. There are some differences if you seek government support while out of work (e.g. jobseeker's allowance or universal credit), but your right to work is in no way limited. If in doubt, check for yourself on the government's site: https://www.gov.uk/legal-right-work-uk
You may also (but are not obliged to) apply for a registration certificate which proves your right to live in the UK as an EU citizen: https://www.gov.uk/eea-registration-certificate
As a EU citizen you primarily need 2 things sorted to work in the UK:
- NIN (National Insurance Number)
- UK bank account
Although you can start working without any of the above mentioned you will need to sort them out as soon as you can.
