EB1 Promotion after I-140 approval, I-485 not yet filed?

[MaryBloom23]

Hi,

My I-140 under EB1B (assistant professor) was approved in 2018, but the priority date or even date of filing for I-485 has not been current since then. So I haven't been able to file the I-485. I understand AC21 applies when AOS is 'pending' for more than 180 days. Does this mean I-485 should have been already filed, or does this apply even if one has not been eligible to file for AOS for several months after approval of I-140?

1) Is there a need to redo I-140 under EB1-B (promotion from assistant professor to associate professor), if there is no change in job duties, the only thing that changes is salary?

2) Can I accept the promotion before or after I file the I-485, without any other change to the GC application process?

3) I am on H1B extension based on I-140 approval. If my priority date is between the 'date for filing' and 'final action date', I am eligible to at least file the I-485. But can I then request a 3-year extension for the H1B, if the I-485 is filed, but PD is not current?

Thanks!

I am in a similar situation as well, only my title has changed from Post-doctoral fellow to Scientist. I am working on filing I-485 for the first time now and any information on how to file I-485 the new title would be helpful.
