A friend of mine in Russia wants to come to California for college. The college accepted his application and he obtained full financial support. They issued I-20 and he went to the interview. His F-1 application was immediately declined. The letter read "you were not able to demonstrate that your intended activities in the United States would be consistent with the classification of the nonimmigrant visa for which you applied."
He wants to try again for the following academic semester. The college extended his acceptance and issued a new I-20. What does he need to provide or demonstrate for the application to be approved?
1) Would this be an accredited institution?
2) What is his major? Would he be a full time student?
3) What does he plan on doing with this degree when he returns to Russia?
I am going to assume that it's an accredited institution and that he has been accepted as a full time student in a real major.
I suspect that the sticking point is that his "intended activities" are more in line with that of an immigrant vs nonimmigrant - there is concern that he is not intending to be just a student. While one can come here on an F1 visa and upon graduation adjust your status if you find an employer to sponsor you (for OPT or H1b visas, for example), there can be no hint in the F1 application that one's plans include anything but returning to one's home country after graduation.
You friend has to be convincing that he is intending to go to CA to be primarily a student, nothing more. Any work has to be within the constrictions of the F1 visa. (For example, a paper grader, research asst, etc., not to exceed 20 hours/wk. Not acting or programming gigs off campus, or delivery pizzas.)
While Highwayman does have a point, those I have known who were had an issue getting an F1 for financial support reasons were told so explicitly.
