情况出现，140被revoke掉了。是不是以前的priority date 都不能用了？
-It does not affect the PD because the revoke is not based on fraud.
这可麻烦大了。我现在的140都是以那个延期的。是不是这几年也成了非法居留了？
-Not affect your previous or current status, but you can not use this revoked I-140 to extend your H1 any more.
有无办法避免？比如，现在就把H1-B 转过去工作。第二次reference的可能性有多大?
-It does not make a difference beucause this is the I-140 sponsor's ability to pay issue, not your work for the employer.
One possible way is that if you may work for the I-140 sponsor for 180 days or more, you may use the benefits of the AC21job change rule (I am not very sure this and you may consult some lawyers to make sure it).
