大俠們j1waiver後是不能離開美國的？

我偶然在UCLA 的王頁上發現這條說明，很緊張，

Q: Can I travel of the U.S. after I have received my waiver approval of the Two Year Home Residence Requirement?

A: Once you or your dependent(s) travel and re- the U.S., you or your dependent(s) will be subject to the Two Year Home Residence Requirement all over again.

我project number 沒變，

豁免之前j1續了一次，給了5年，所以我就去辦了豁免

我現在打算讓老板辦h1b了，同時開始綠卡申請
如果這屬實，非常麻煩，據說辦兩次waiver很困難，而且我時間也耗不起。。。。
