Will H4 affects when Employer B revoked H1B

[krishsm]

Hello All,

Can anyone please shed some light on this?

Employer A:
1. Having approved I140, applied H1b petition on May 2013
2. Received H1b petition approval from 10/2013 to 09/2016.
3. Applied H4 at the same time and received approval from 10/2013 to 09/2016.
4. Work location changed, so applied H1 amendment, received H1B approval from 04/2015 to 03/2018

Employer B:
1. Applied H1B transfer on May 2015, received approval from 07/2015 to 12/31/2017
2. Applied H4 along with H1b transfer, received approval from 07/2015 to 12/31/2017 (Attorney filed H4 along with H1B transfer).
I did not join Employer B and continued to work for Employer A.

I applied H4 EAD for my spouse on basis of my approved I140 and received approval till 12/31/2017.

Now I just came to know that USCIS has revoked the approval of my H1B petition that was applied by Employer B on Jan 2016 as I did not join their firm. No issues with this revoke as my Employer A petition is still valid and I'm still having valid petition from Employer A (i.e., till 03/2018). 
I further checked USCIS website to verify the Employer B H1B petition: It says 'On January 28, 2016, we revoked the approval of your case'. H4 petition status still shows "On July 8, 2015, we approved your Form I-539, Application to Extend or Change Nonimmigrant Status"

I know H4 petition is only tied to Primary and not to Employer but now my concern is that when Employer B revoked my H1, will that invalidated my spouse' H4 approved petition that was filed along with H1 transfer?

Can someone shed some light on this, please?

Thanks,

Krish.
