@Diplomatru, he might not be successful either. These five countries: USA, Canada, UK, Australia & New Zealand share information about visa applications through their joint database. Although, this's arguably meant to crack down on terrorism, but it's widely used for other purposes. If the reason for Pravee1989's refusal of Canadian study permit is colossally substantial, then the US will also likely deny him F-1 visa. It always works that way. Moreover, if for instance, Praveen1989 was refused a Canadian study permit owing to insufficient fund, but now has an admission with full funding at a US institution, then there's a high balance of probabilities that his application for F-1 visa will be approved.
So depending on the magnitude of the overall circumstance under which Praveen1989 was refused, his application to the US embassy may be easily rejected in the same way or otherwise approved. That's why it's absolutely indispensable that Praveen1989 analysed his situation critically before applying to any of the aforementioned countries.
