大侠们j1waiver后是不能离开美国的？

我偶然在UCLA 的王页上发现这条说明，很紧张，

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 没变，

豁免之前j1续了一次，给了5年，所以我就去办了豁免

我现在打算让老板办h1b了，同时开始绿卡申请
如果这属实，非常麻烦，据说办两次waiver很困难，而且我时间也耗不起。。。。
