What i found concerning was if i had not been there personally with my fiance at UKVACs, she may easily have been convinced by those in authority to just send what was asked for on the application. She had the awareness after reading petes site and from our preperation thanks to what we've read here to know we were right in what we had with us. What i actually had with me was at least 5-6 double sided A4 sheets of small print for every days chat we had, which was almost every day for 16 months, I fully agree with you pete that the evidence is one of the most important things we had to submit, and even though i removed some, i still submitted evidence to show contact every day for that period, plus a summary showing so. This took quite some time to do while waiting in the hall at UKVACs, as the sponsor is'nt allowed into the office there either. I doubt if a courier will be willing to wait while you do this.
When our originals were returned, the chat transcripts were not with them, so those that we removed will be taken to the interview to back up those that we sent originally. As u say the UKVACs officials dont really give a toss what u submit. Our paperwork was'nt even checked by them at submission at the desk, just asked was it there and ticked off the sheet. The sorting of the docs was done after we left in a back room by someone who we never met.
I appreciate what those who have gone before us went through in the early system, for without them we would'nt stand a chance.
