非常感谢您费神回答我以下的问题。您给的link, 好像缺了字母，did not work。能否麻烦您一下？我需要USCIS的文件去说服学校的legal counselor--他们都是死脑筋，非得见到文件才行的。

不知现在Eb-1b形势如何？如果被拒，应该不会影响原来的PERM-based I-140申请，对吗？
再次拜谢。

1） 移民局哪个文件说可以file multiple I-140? 而且file Eb-1b I-140 并不会影响原来PERM-based的处理？我得让学校的legal counselor 看看。
-There is no specific USCIS文件 on this issue. But there is also no legal prohibition for a person to file more than one I-140 petition.
Here is a USCIS document concerning priority date portability (actually it is related to multiple I-140s.).
http://www.uscis.gov/files/pressrele...22_091206R.pdf
A quote from page 28 on Priority date determination is as follows :
Company A files a labor certification request on behalf of an alien ("Joe") as
a janitor on January 10, 2003. The DOL issues the certification on March
20, 2003. Company A later files, and USCIS approves, a relating I-140 visa
petition under the EB-3 category. On July 15, 2003, Joe files a second I-
140 visa petition in his own behalf as a rocket scientist under the EB-1
category, which USCIS approves. Joe is entitled to use the January 10,
2003, priority date to apply for adjustment under either the EB-1 or the EB-3
classification.
2）看到可以 e-file online，这跟paper filing， 有什么优缺点呢？选哪个好呢？
