Can i try to become an IFS officer when there were some unislamic practices (like difficult in managing spouse, parents & childrens, shave beard..etc) but will gain serve to ummah...?? Please give an advice on the view of Islam...?

I am intended to do Civil service examination to become an IFS (Indian foreign service officer) with the intention of serve ummah. The job structure is we must reside from foreign countries to country where according to government appointment until death. And the way of managing wife, children & parents are very difficult. And also we must forced to remove beard and don't have chances to wear sunnah dress until retirement and the government also provide a luxury life. But the only positivity is i can serve the ummah with the provided governmental power & can stand for justice.
What is the Islamic view for doing such job by considering above all aspects

In the current situation of India the presence of Muslims is essential in all senior positions so shaving is permissible for getting the post like Indian foreign service and it is also important to pay  maximum attention to your responsibilities to your family as you can.
