What are the options for fellowships for international grad students in USA? I'm looking for fellowships that an international grad student can apply for, to support him/her while working towards a Ph.D. (additional to whatever funding that may be available as TA). So far, I've been able to identify the following:


Fulbright Scholarships for International Students (applications have to be done more than a year before, and they've suspended 2013-14 grants, so not really an option for me)
Aga Khan Foundation International Scholarship Programme, which has the following selection criteria:



  The main criteria for selecting award winners are: l) excellent academic records, 2) genuine financial need, 3) admission to a reputable institution of higher learning and 4) thoughtful and coherent educational and career plans. Candidates are also evaluated on their extra-curricular interests and achievements, potential to achieve their goals and likelihood to succeed in a foreign academic environment. Applicants are expected to have some years of work experience in their field of interest.


It would be great if I could get to know of similar fellowships that an incoming student can apply to, before starting grad school.
The Smithsonian offers fellowships for international grad students, specifically a ten-week summer internship for pre-dissertation grad students and 3-12 months of funding for post-dissertation grad students. Also, you get to work at the Smithsonian.
