Dear Shashwat,
To get a job in UK is not easy now. Post study work options for international students have been tightened, please follow news and updates and visit UK immigration websites for details. Which course you should do, is your choice. You can consider:
1. Finance.
2. Accounting.
3. International business.

Dear Rajas,
If you are looking for post study job option, then Australia would be a better option as work permit option in UK is very tough now. IELTS is required for international students. You can check the university websites for admission requirements.

It will cost you around Rs.5 crore to Rs.6 crores.
Good luck.

UK will not offer any jobs to international citizen. You can look for another country.
Good luck.
