你现在485 Pending 180天以上是可以换相同或相似的工作,但需要USCIS批了你的140。 USCIS是这么说的: https://www.uscis.gov/forms/petition-filing-and-processing-procedures-form-i -140-immigrant-petition-alien-worker If you request to change jobs or employers under INA 204(j) while your Form I-140 is pending, we must approve the Form I-140 before we may approve your portability request. If your Form I-140 is pending, it must have been valid when filed. This means that at the time the Form I-140 was filed, you must have been eligible for the employment-based visa classification and had a valid job offer. 所以你的AOS能有port成功,取决于(1)你的EB3 140能批,(2)485已经Pending 180 天以上,(3)你现在的工作和原140申请时的工作是相同或相似的工作。 你应该和公司律师分析一下你的情况。如果有问题,应尽快让现雇主申请H1B来确保你 的身份没问题,有时间重新走PERM。(既然是降级的EB3,应该有已经批准的EB2 140吧 ,可以用来申请H1B。)
