US Immigration from Brazil

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

my fiance already has both shots for the covid virus. I was wondering, for the K1 Visa if she could get the MMR, Tetnus, Hepatitis B Etc vaccines in Brazil prior to her interview. I was wondering if that's acceptable.. Or does it have to be in the united states. Than you
