I'm pretty sure you can find the answer here. Find your embassy in the list, click and it will tell you where what to send

She is correct and I sent you the same link in your other post. Just remember to make two or three copies of everything you send in so you have your own record of it all and also so you can take it with you when your interview is scheduled. Just because you have sent it all in to the NVC - does not mean it will actually show up at the interview, so better safe then sorry to keep all copied and in your own folder, just in case you are asked for it, you can show you did it. You will be sending it all into the NVC. DO NOT FORGET the NVC case number on the top of every piece of paper you send in. Good luck!

Yes, the link should answers your questions.
