Hello Sir
Every university has its own eligibility criteria to grant scholarships to international students, in order to know the exact eligibility criteria it would be always advisable to browse through the university's website you wish to apply.
Overall, scholarships are competitive and awarded to the most deserving students. At the graduate level you can get funding in the form of graduate assistantships where you work or research with professors. In exchange you may get your entire/partial tuition fees waived, and get a monthly stipend to cover your living expenses. Such awards are very competitive.
Universities abroad consider various factors such as previous academics, entrance test scores, work experience, application documents and so on while assessing an application for admission and scholarships; hence, it is important to have a well-rounded outstanding profile.
