Former Costa Rica President and Nobel Peace Prize winner Oscar Arias says the U.S. government's unexplained cancellation of his visa won't stop his public criticism. Arias received an email from the U.S. State Department notifying him of the decision, which stated that he may be ineligible for his visa. Arias believes the decision may be related to his comments on various global issues. Despite the visa revocation, Arias remains unfazed and continues to admire the U.S. and its people.
