Revocation of I-140 - New Rules

[Artless]

Recently I learned there are new rules that petitioning employer cannot revoke I 140 if I change employer after January 17th.

My question is if I change employer before 17th January 2017 (lets say 15th December) and my employer haven't revoked I 140 by 17th January 2017, can he still revoke after 17th January 2017 even if I left him before 17th January?

No such rule. In fact the situation may become more dire after the inauguration of the next great hope for the world.

I also heard that there is going to be a such new rule, The following is the link to the same:

https://www.federalregister.gov/documents/2016/11/18/2016-27540/retention-of-eb-1-eb-2-and-eb-3-immigrant-workers-and-program-improvements-affecting-high-skilled

Although, I am not entirely sure if its true, i.e., employees get to avail the advantages that come with an approved I-140 even after the employers withdraws or revokes the I-140 petition, the benefits include unlimited extension of H1b in the increments of 3 years, priority date retention but I am not sure of H4-EADs which are tied to these approved I-140s.

 

Please correct me if I am wrong.
