Former Costa Rican President and Nobel Peace Prize winner Oscar Arias says the United States has revoked his visa without explanation. Arias, 84, has been a vocal critic of former U.S. President Donald Trump and has maintained diplomatic ties with China during his time in office. The visa cancellation follows similar actions against other Costa Rican officials who opposed U.S.-aligned policies, raising concerns about political motivations behind the move. Arias stated that the revocation will not silence his criticism. The U.S. State Department has not publicly commented on the reasons for the decision.
