How to withdraw H1B petition after the greencard is received

[edd.har]

I just got my greencard (yes, the card). My employer already applied for H1B several months ago and have not heard anything about it. How can they withdraw/cancel the H1B petition?

Thank you.

your employer can write to CIS.

---------------do nothing as USCIS is not going to send the Fee Back to Employer
Thank you.

if on the Form I-129 lawyer wrote your A# then USCIS Will deny the H1 extension they will come to know this with your Name, DOB or A# that your I-485 got approved
