The degree of B.Sc is universally accepted worldwide if it is received from an accredited and renowned university. Countries like the U.S., Canada, the U.K., Australia, and Europe typically accept B.Sc. degrees for further studies or job opportunities. However, there may be requirements from specific industries or employers regarding credential evaluations or licensing exams prior to accepting a foreign degree.
It differs from field of study and the regional education policies. In some countries, holders of a degree may be made to undergo equivalence tests or even further training in certain areas before one can go ahead and either seek higher education or employment. If you wish to work or study in another country, do not forget to check on their recognition requirements of your degree. Organizations like WES (World Education Services) help assess the degrees for international recognition purposes.
