Yes I have a 3 year B.S.c and a 1 year M.S.c both from universities in the UK, along with 9 years experience with my employer, an EU firm I worked for in the UK that subsequently asked me to transfer to the US 5 years back. My master degree is directly related to the field I work in, and to some degree so is my Bachelors. However the role I perform and pretty much every role at the firm usually only request undergraduate degree and experience so as such my employer has applied for EB2 as BSc plus 5 years. From what I have understood there are rumors that USCIS may not consider a UK 3 year degree equal to a 4 year US degree. My employer along with the legal firm that represent us meticulously pointed out the difference between the UK/US education system and explained in detail the role of A-levels etc and generally the UK having one of the highest university standards in the world. I am told this is usually sufficient as the firm has applied for a few GC in the past with generally no issue. As you can see from my stats I am still pending I-140 approval, so I cannot comment on how my case will be treated by USCIS but I don't believe they all get rejected.
