It's great that you are planning to pursue your higher studies with BSW or BA in English as your career options. Now if you really plan to go abroad , it's a suggestion that if you have immense interest in Social Work then do the BSW course and there is high chance that you can enroll yourself in fully funded Master's degree programme in future. As most of them have the eligibility criteria of being a social worker and they will look forward to what contributions you made to the society. But BA in English is also a good option to choose , but BSW is a better choice.

Best Wishes!!!!
