Does wearing the niqab prevent a female engineering student from finding a job or achieving her dream of becoming an Islamic preacher?

Scholars differ on the obligation for a woman to cover her face in front of non-mahram men when there is no fear of temptation, and what is fatwa-ed by us is the obligation. Covering the face is better for complete protection, perfect modesty, and emulating the Mothers of the Believers. The niqab is not a hindrance to work or an obstacle to da'wah; rather, it is more obligatory for the female da'iyah and more helpful for her da'wah. We advise being diligent in covering the face from non-mahram men, except out of necessity or a recognized need that is estimated according to its measure.
