i140 : We mailed you a Withdrawal Acknowledgment Notice

Hello Rajiv sir,

Below are my questions related to i 140 and H1B extension beyond 6 years:

A) i 140 approved (have a copy ) from Company A on December' 22nd 2017. I have changed job to company B on October' 12th 2018
Recently, checked my status in USCIS website (using i 140 receipt number) and found:
"We mailed you a Withdrawal Acknowledgment Notice"
Question: How will it impact my future extensions with company B (current employer), using company A, i140 ?

B) If I plan to go back to India for 3 years, and work for company B(offshore), or C. and
Thereafter, If I wanted to come back to USA using Company A , i 140 through company D , will it be possible? or what all options do I have?

Thank you,
