I was working in H4 EAD and got my H1B selected through lottery in 2020. I applied for my H4 extension through my spouse in August 2020. Meanwhile I got my H1B approved and I am in H1B status from October 1st, 2020. Immediately I also sent a withdrawal mail to USCIS for H4 petition on October 2020.
Now I received my Biometric appointment for H4. Immediately after the notice, I reached USCIS and they mentioned that they have not received my mail, so I resent another withdrawal mail on April 26th, 2021.
What should be my next steps? Should I attend my Biometric or skip it?
