Fair enough. You need to contact the Royal Pharmaceutical Society (
Rpsgb.org: Contact us) about the legal issues. I know Romania is part of the EU, but in the back of my mind there's something special about working requirements.
As regards employment, if you want to work in community, then contact one of the big chains (Alliance-Boots, Lloyds, National Co-op, Rowlands). If you are interested in hospital, then decide roughly where in UK you would like to go, find a hospital (or hospitals) in that area and contact the pharmacy dept direct.
