Hi there, I've been following this thread for a few months now. It really helped me out at times to go through this process..I applied for my husband in May..his interview is on February 7th..we got the notification last Tuesday..on the letter they also stated that the documents must be received by January 22, 2018...original birth and marriage certificates along with his passport..but the letter also states that he should bring them to the interview which is conflicting. So I emailed kingston and got a reply same time..they told me that my husband should bring them to the interview not drop them off by the date as specified in the letter.. so I dont know why they would put that in the letter...maybe you should email them to confirm..
