FINANCIAL AID In USA
It is important to understand that most universities offer financial assistance to international students based primarily on merit and rarely on need. The amount, and type of assistance offered varies, based on the university, department and level of study. Assistance of funds is more likely in Graduate studies and less in Undergraduate courses. Also funds are more likely to be available in fields like Engineering, Physical Sciences and Biological sciences, rather than in courses like Humanities, Social Sciences and Management.
In contrast to undergraduate education, where admission and financial awards are controlled at the institutional level, US graduate education is quite tightly controlled at the departmental level. Funding for certain fields tends to be more heavily subsidised than for others. For example, a student of physics, chemistry, or biology may find institutional funding more readily available than a student of humanities, the social sciences, or education.
