I had the additional documents with me and I showed them to the officer. The officer was happy about them but they asked me to upload them to CEAS and gave me 221g, I then uploaded the documents to CEAC on the spot.
Along with the 221g they gave me a form with instructions, the last instruction is to send the original documents to the embassy via DX delivery. Which I did. My questions are:
1- Did I have to do this (send them to the embassy via DX)? since the officer already looked at the original documents in the interview, but they were only concerned that they weren't uploaded?
2- Also, I sent original documents, and I need them for the future, does the US embassy return those documents along with the passport?
3- And if so how long does the US embassy in London usually take to change the status for such scenario from Refused to Issued?
Thanks in advance!
