As a graduate student with an admissions application on file, you are automatically considered for graduate financial support in the form of grants, stipends, and the like. (You can view the eligibility criteria and contact information for the types of support on the Graduate Financial Support Contacts page.)
Additionally, as an NJIT graduate student, you can apply for supplemental funding in the form of an education loan, including such as a Federal Direct Loan, Perkins Loan, or a private loan—by filing a Free Application for Federal Student Aid (FAFSA). Once your FAFSA is on file at NJIT, you will automatically be awarded Federal Direct Loans, either subsidized or unsubsidized, based on your eligibility. (You are free to decline the loans if you do not want to receive them.)
Keep in mind, though, that all graduate teaching and research award decisions are made by the individual academic departments and not the Office of Graduate Studies. (As such, the terms and conditions of the awards vary.) Also please note that financial support is generally reserved for those students pursuing a doctoral degree.
