计划年底过来待到明年六月,护照明年八月过期会有问题么?
-Most likely the duration of I-94 will only be two months because it is required the passport has to be valid for at least 6 months beyond the intended stay time. That means if you want to stay in US for 6 months, your passport has to be valid for at least one year before you enter US.
还有一个问题就是五年有效的护照是不是可以延期?
-不是延期, but get the new passport after this one expires.
