Hey guys i’m really confused about the type of financial aid offered by Stanford university to international students ,some people claim that Stanford offers Need Based to international students but it is very competitive and you need to be a very competitive student, the thing i want to know is what type of aid does Stanford offer to international students ? and will Stanford meet the full demonstrated need ?
PS : i’m an international student. 
Stanford offers financial aid for Internationals but they are not need-blind meaning that as an International applicant requiring financial aid, it will be considered in your admission chances. If you are accepted, then they will meet need.
From the website:
Financial Aid
Regardless of citizenship, applicants are reviewed in the context and country where they attend high school. In addition, Stanford is committed to meeting demonstrated financial need for all admitted students (regardless of citizenship) who have requested financial aid during the application process.
If you are not a U.S. citizen or U.S. legal permanent resident, your request for financial aid will be a factor in our admission evaluation. Because of the limited financial aid resources available to international citizens, Stanford can offer admission with financial aid to just a small number of international citizens each year. International citizens who indicate on their applications that they will not be applying for financial aid and subsequently are admitted are not eligible to apply for financial aid at any time during their four years at Stanford.
Essentially what it means is that they are limiting the amount of money available to international students and they will stop admitting students with a need when they run out of that pool of money.
Needing financial aid lowers your chances of admittance. The more financial aid you need, the harder it will be to get in. Very, very few international students receive full financial aid.
