Hey,
Zeta Psi Fraternity (
http://www.zetapsi.org/ ) does have an existing chapter in England at Oxford University. It is our Iota Omicron chapter. So it is possible. As far as I know we are the only one with any chapters in England. Zeta Psi is looking at other international chapters. Potential chapters must meet certain criteria to be accepted, as do the universities we choose.
Here is the contact info for starting a chapter of Zeta Psi. From what I understand we have about 8-10 requests a year for perspective chapters. We usually only accept 1 or 2, as the Fraternity is choosy as to what universities we go to. In the USA the criteria is top 100, in Canada it is determined partially by ranking, programs offered etc. Not sure what they are looking for internationally.

I am sure since we have a successful chapter in England there may be others looking to make the move overseas as well.
