Change Employer And 485

[kaliamama]

Hi any help will be greatly appreciated.
==================================

Current situation:

1) Chang H1 from company A to company B. (h1 WITH CO B NOW )
2) I140 from company A is approved and PD is current.(after the big jump of PD on this month's Visa Bulletin)


Question:

1) How likely will USCIS find out and reject my I485 based on change of employer?
2) If the I485 is rejected, will it affect new/future application of GC (assuming pentitioned by company B). Will I be in some sort of blacklist?



I understand that the general advice is NOT to change job now, but I've agreed to them and they have prepared everything for H1 Change, plus...I really like the new job.

Thanks!!!
