There are available working Opportunities in Bangladesh. For public and private university students, there is a career counselling centre. Students from a different country can also work in their embassy, and they can also get support from there. In some cities your can-do part-time work and your University won't create any problem and the best part is there is no working limit here.
For medical students, there are internship possibilities also. Again, after completing MBBS and BDS degree, they can practice here.
