Pretty sure Romania is in Schengen. As someone that spends more than half the year in Romania I know I hear it mentioned a lot.
I nearly f. this up when I was traveling with my Non-EU girlfriend who was on a single entry Visa and I was about to book a flight for us from Vienna to Sofia to travel in East Europe.
The question is: Can citizens of Bulgaria and Romania just move to the UK without further requirements? Looks to me they would need a visa.
Yes. This right has nothing at all to do with Schengen.
The transitional restrictions for Bulgarians and Romanians, implemented when the two countries joined the EU, ended on 1 January 2014.
