I would like to hear about your experiences of applying to PhD programs in the USA.
Is it complicated to get accepted? How much documents and preparation is needed?
Did you or your friends have succeeded?
From the sayings around by some friends, I think it is harder if you dont come from an English speaking country or a more western country. There is the issue of passing the English test etc. Then, after that, another thing is the fee that are really high in the US. If you dont get a funded PhD position, it could be expensive.
