hey dude, the better idea would be join MBA after completing BBA at nepal. normally if she has 4 yrs that would be perfect bcoz 3 yrs bba at nepal are not fully credited and if she is trying to join MBA with 3 yrs BBA here, Most of the university gona make her to join PRE MBA. thats too boring and useless so its better to have 4 yrs bba and come here. secondly make sure she has GMAT. most of the university requires GMAT for MBA. and if she have good GPA and good score in GMAT , she can apply for graduate assistanceship if not she will have to work off campus being a full time and MBA isn't easy with being full time working off campus.. specially for girl.
