对，就是因为那些人不停投诉所以导致拿F签的学生不能参加TST。

For the IMO, EGMO, RMM, TSTSTs, and TSTs, students must be US citizens or US permanent residents. Visas are not a valid substitute.

但是参加USAMO并且评奖的资格是有的

U.S. citizens and students studying in the United States and Canada (with qualifying scores) are eligible to take the USAMO and USAJMO.

至于MOP，好像去年是不可以，今年又说可以了。
