All International students need F1 VISA to study in any of the US universities. Student VISA to USA is very simple; yet very difficult to get! You can start your VISA process once you receive an admission (I-20) from the university. You will typically have to attend a personal interview at the US Embassy / Consulate for obtaining a F1 VISA. Outcome of the VISA is completely at the discretion of the VISA officer. You will be interviewed by the Consular Officer and based on your answers and paper work they will take a call on your F1 VISA. During the interview, the Consular Officer will evaluate your case mainly observing your intent to visit the United States, your academic and financial background, your travel history and several other factors. If the F1 VISA is approved, then the Consular Officer collects the passport to print the F1 VISA on it and will return it back to you through courier. You will get to know the outcome of the F1 VISA on the same day of your interview and it might take around 5-6 days for them to send the passport back to you.
