If I get a computer science degree from uopeople, can I use it to apply to graduate school in the US? As i know, uopeople has only DEAC accreditation, but still does not have regional accreditation. Can i qualify for getting any scholarship?
Probably not. Most graduate programs require a bachelor’s degree from a regionally accredited college, and even the ones that don’t explicitly say that (although most do) will probably not look favorably upon a BA from University of the People.
And what about European universities with a similar program? For example, if i get a BSc from University of Hertfordshire http://www.herts.ac.uk/courses/bsc-hons-computer-science-online that will be enough for admission to graduate programs in the US?
Yes, you can get a BSc from a foreign university and still go to an American university for your graduate degree.
