<p>Yes, officially scholarship candidates are required to come to USC in late February or early March to interview for the scholarship. It is part of USC’s desire (and strategy) to award their top scholarships to applicants who sincerely are considering attending USC. Making the trip implies that USC is a school they are seriously considering.</p>
<p>There have been individuals here on College Confidential who have contacted USC and managed to communicate both their desire to attend USC and their inability to attend the interview sufficiently to be allowed a Skype interview, but there have also been individuals who asked for that and were not allowed to do so. It depends on the reasons you cannot attend. (A bridge to cross when and if it becomes an issue.)</p>
<p>As for the financial document, I recommend you contact USC in early January to discuss that. It is not required when you submit everything else on December 1st, but is required before a letter of admission can be sent, and the scholarship interview invitations are sent AFTER the letters of admission. I know that other International students have faced the same issue, and USC can guide in how to approach the issue. It will have to be submitted by mid-January in order to be invited to interview, so DO get it done.</p>
