请教8老师： 我弟弟两年前在国内拿到美国十年有效的签证，并于一年前来过美国。过两个月他想要再来美国玩两周，机票都买好了。 近来听说美国要取消中国人来美国的十年签证，不知道消息是否属实？
-I don't see any official change about this issue. I have seen some Chinese people always spread this kind of rumors. You had better check the website of the US Embassy in China, not just believe this baseless information from Internet.
如果有这样的说法，那么是取消办理十年签证，还是说已经拿到的十年签证也无效了？
谢谢8老师！祝您节日快乐！
