回复：回复：pjiang， 863211：PD可以保留吗？

Thanks a lot! 多谢多谢！！
我昨天又问了新公司律师一遍，他解释说：
The Regulations have been in place many years and the Guidance letter which was issued later is just that - guidance, that may/may not be followed. In addition, how CIS handles the recapture of a priority date where the I-140 has been revoked is discretionary.
律师的意思是尽管有这个memorandum或者guidance，具体操作时候，不一定按照memorandum执行。这法律叫什么事儿啊，你说是不是。
