Grad School, Grad School, Wherefore art thou, Grad School?

So we’ve been preparing for grad schools. We bought the GRE book, we emailed all of our professors for information about grad schools (and most of them emailed back with terrific information!). So here are our list of candidates (for now, we may or may not add, or delete certain candidates):

1. Oxford
2. St. Andrews
3. University of Connecticut
4. University of Oregon
5. Brown
6. BYU (Provo)

any other helpful hints for us? Anyone know how long it takes to get a student work visa for the UK?
