計劃年底過來待到明年六月，護照明年八月過期會有問題麽？
-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.
還有一個問題就是五年有效的護照是不是可以延期？
-不是延期, but get the new passport after this one expires.
