US Immigration from Brazil

Hello,

I had a combo interview a few days ago (November 2, 2021), I passed and my case was recommended for approval. During my interview I was a little confused about the name change option, I asked if I could add a middle name, but I was never informed that my oath ceremony may take months to be scheduled. I regret it, I realized that it will be very inconvenient to change all my documents and I want my process to be done as soon as possible. Is there anything I can do to withdraw this name change request? I sent a letter to the immigration officer who interviewed me and I also requested an infopass appointment, so far I didn't hear anything. My case status is still showing "interview scheduled". Does anybody have been in a similar situation? I appreciate any help.

Thank you.

Does anyone know if the k1 visa will be processed in an embassy other than Rio?

Does anyone have the contact information for the Embassy in Rio de Janeiro? Sent an email fir anuodate as we are waiting to receive the packet so we can schedule our interview date but they have not responded. Thank you to all.

Does the status of "Ready" mean I can schedule the appointm? Or does my fiance have to receive the packet from Rio de Janeiro first AND do I complete And upload the ds-160 and I-134 befir or after she recieves the mail from Rio? Sorry about all the questions, I want to stay focused and do things the right way so I only do them once. Thank you in advance.

the notice says that my Visa application is in transit to Rio, and that the NVC sent me an interview date. but I don't see any attachment. I don't know where it is or how to find it
