现公司突然冒出来说可以再renew 3 年H1B，傻了！
09年2月被擂，当时在那个公司approved I-140 EB3现在在网上查也没被revoked掉， PD: June,2007
之后来到现公司，给办了H1 transfer, 但不sponsor绿卡，出于各种原因吧，没找到也没仔细再找能sponsor绿卡的公司。马上6年大限到了，想着能回国陪老人家也不错，没觉得有太大遗憾，结果公司律师颠颠地来管我要材料renew h1b, 我跟他说没得延，没时间了，人家硬说可以，blah了一通。
Unless the prior employer retroactively withdrew the already approved I-140 petition, he is mistaken. In fact, we relied upon the approved I-140 petition to get a three year H-1B for him when we initially applied for H-1B status. While XXXX(现公司） cannot rely on the approved I-140 petition for the prior employer for permanent residence purposes, we can still take advantage of it for H-1B extensions, provided Mr. XXX remains ineligible to apply to adjust his status because of the unavailability of permanent resident visas. The I-140 petition was approved for a third preference professional. He is a national of the PRC. Permanent resident visas are available for third preference aliens from China with a priority date of March 1, 2005. (That will change to April 1, 2005 on May 1.) Mr. XXX’s priority date is June 12, 2007. We can therefore use the approved I-140 to extend his H-1B for another three years, unless somehow his priority date becomes current before September 2012（六年大限期）.
Theoretically, at some date in the future Mr. XXX could rejoin his prior employer in the same or similar position that was the subject matter of the labor certification application and I-140 petition, and, when his priority date is current, apply to adjust his status. He simply cannot use the approved I-140 for an I-485 application if he is not working for or rejoining the prior employer.
大意就是你反正有一份没被revoke的I-140, 在你的PD current前，你都可以3年3年地renew h1b, 不管employer 是谁。PD current了，你可以回原公司工作，继续递485，办绿卡。
请问老师，这律师哥们说得对吗？我真是闻所未闻唉！
谢谢！！
