Old h1b revocation notice

i have current valid H1b till 2017 and my visa is being transferred from company A to Company B before 6 month .

but one month before i got an email from USCIS that my old application has been reopened again and Yesterday i got an email from

uscis that my old application has been revoked and they will mail me reason on march 31st .

so my question how it will affect my current h1b application ?

Here is email text:

Your Case Status: Post Decision Activity On March 17, 2015, we revoked the approval of your case, Receipt Number XXXXXXX and mailed you a revocation notice. It explains the reasons for our action. Please follow the instructions in the notice and submit any requested materials. If you do not receive your revocation notice by March 31, 2015, please go to www.uscis.gov/addresschange to give us your new mailing address.

Please reply asap.

Thanks in advance

There are two types of revocation - Employer Revocation and USCIS Revocation

USCIS Revocation - This happens when your employer/you fail to submit docs for RFE or at the time of stamping (221G). In this case, your petition can’t be used for cap-exempt

Employer Revocation - This is done by employer when you quit job or they felt that they don’t need you

In your case, I see that you left company A and as such they have withdrawn/revoked your h1 and it’s quite common…No worries
