Just heard back from an international advisor from another university. He said that a student doesn't need to have an I-94 to leave the country (I'm not sure if it applies to other visa status' as well). Saves me the hassle of going through the whole I-94 replacement process, and a few bucks too. Anyways, two advisors saying the same thing makes one feel more confident that they know what they're talking about (I've heard of instances where advisors providing false information has led to many a problem for some). Again, thanks to all for their views.
