Recognition of a foreign degree, however, is decided by the authority of the country where you intend to use it, not by the university that issues it. Some countries also exclude certain fields: India’s UGC, for instance, does not recognize foreign online degrees in law, medicine, pharmacy, nursing or architecture. If your plan depends on recognition, check with the authority in your country before you enroll, and ask an advisor for the documentation they will need.
