USA

Hello,
A number of factors have to considered and prioritized when you make this decision. Studying abroad is a wonderful opportunity to gain international experience and exposure to various platforms in terms of culture, jobs, opportunities etc. However you need to enroll into a well known university for better prospects after you complete your studies. Studying abroad is also expensive. Research more on the admission requirements, budget, post study work options. If you have a competitive profile well suited for IIT you need not think beyond, an IITian is globally accepted. For anything below IIT you can consider a top ranked US university counterpart.

Hello, You should choose a course on the basis of your interest and not for only settlement. I am sure while you may select the course for which you are interested, you may end up performing it better academically. More than that, it depends on your interest and background as well. If this is a Masters which is STEM focused, you may have up to 3 years of stay back in USA and MBA in most cases would be a 12 months only. So, you are suggested to see your background of education and your interest in pursuing a technical course of Masters in the same/similar field or you have a few years of work experience and now, you may want to learn and excel in management skills, then MBA suits the best as it will give a better growth to your career. All countries will have their own perquisites and standardized test requirements which you should be taking like GRE, GMAT, IELTS or TOEFL before you apply.
