Aberdeen is a GREAT acceptance, part of the " Four Ancient ones" … but not really practical. None of your credits would transfer and it’d be really difficult. You’d have a “6th century” seminar and 3 other courses each semester, about 12 hours of class, lots and lots and lots of reading and the equivalent of a final paper every month in every subject, little to no advising, some support (a mentor and tutors).
Unless you’re 100% sure you want to study in Scotland and get a Scottish degree, you’re better off spending a semester in Scotland and, if you really loved it, returning for a 1-year Master’s degree. 
With Loyola NOLA, you can do “direct enrollment” at the University of Edinburgh. In addition, they have lots of programs with Ireland, Spain, South Korea…
With Penn State, you have
- embedded programs: you take a regular course on campus and it includes a study abroad component.
There’s a program for Schreyer scholars and Paterno Fellows* where you complete the Arts Gen Ed requirement then go to London to see plays, visit, and then on to Edinburgh.
- you can participate in summer research at Aberdeen (Biomedical sciences) or Glasgow (STEM, psychology, geography)
- you can spend a summer or a semester abroad especially designed for future business majors, in Australia, in the Czech republic, Paris, Amsterdam, Lisbon, Barcelona, Singapore…
DUS is what students are before they’re allowed to “progress” to their major. You need to complete some pre-reqs and you’re only admitted to Smeal once you’ve passed them all and have a 3.2 GPA (Finance is higher). There are alternate majors such as SODA, Economics, Labor Relations, Organizational Psychology, Environmental Business, Enterprise Design Integration…
Loyola is much smaller, Jesuit, humanistic, in a nice area of a great, historical city. Smaller classes, more personalized advising.
Penn State is a huge university, with over a hundred majors, large classes unless you’re a Paterno Fellow Aspirant*, a big sports culture, lots of “school pride”, in a college town.
*Paterno Fellow Aspirants: declare they want to take up the challenge and by that declaration are made “aspirants”. They take Honors classes and seminars alongside the Schreyer scholars and in order to “stay” in the Honors College they must meet certain grade requirements. They can take (say) Honors Economics in a small group where they know everyone, instead of being in a large lecture hall. Paterno Fellows Aspirants can be DUS if they suspect they may end up choosing a major from the Liberal Arts. If, after 3 semesters, they don’t, they’re no longer Paterno Fellows (but at that point they’ve either realized they like a major in CLA or no longer need the special classes in Schreyer.)
