Is it possible to request information from an college located in Engalnd. For instance (Oxford,Cambridge, and London)
Yes, but everything you need to know is online. Truly. Every course, down to the most of the modules you take each year, prerequisites for application, what you need to have to get admitted, everything. It is actually pretty great, and there is much less guesswork than for US colleges. Not sure which London university you mean, but aside from Oxbridge & LSE if you have the required marks, and the rest of your application is reasonably strong you have a good shot at an offer.
However, neither Oxford nor Cambridge has a Journalism or Communications course (I peeked at your other posts), and if you want to do something like English or History you should take a serious look at the course description. It is much more intense, and a lot more prescriptive than in the US.
I do know a History student at Oxford who has a job offer at one of the major London daily newspapers for after he finishes in June, which he got partly through people he met at university who had connections and partly by being ruthless as a student journalist. You would want a very hard neck to play in that pond.
