Summer programs for European undergraduate mathematicians There are many summer programs in the US, aimed at motivated undergraduate students of mathematics, that offer lectures and mini-courses on a variety of topics. However, as far as I know, most programs require that the applicant is American or a permenant resident in the US. 

My question: 


  Are there any such summer programs in the US, Europe, Asia, South America,
  or Africa to which a European student can apply?
Park City summer program organized by the IAS (Institute for Advanced Study, Princeton) is worth trying. In particular, they have Undergraduate Summer School. Here is their Application procedure.

However, non-US permenant resident/citizens may have to pay more as in their web page


  Undergraduates funded by PCMI may receive lodging, travel, meals and a stipend (stipends are awarded to U.S. Citizens or U.S. permanent residents only).


Please note that the application deadline for 2015 is already passed (January 31, 2015).
