As someone who will be flying in from the US, the 200 dollars is a reasonable and helpful amount. Flying crosscountry without it would be hard.
I think the concern of an international student is valid.
If you can suddenly budget $2000 (I use the amount mentioned earlier) to fly for two days to another country, than more power to you. I could not come up with that money, and I wouldn’t be applicable for too much Financial Aid. It’s sad for international applicants frankly that there isn’t more assistance. If USC had said they would provide half the airfare, that would have been better for everyone.
