sorry for the delay in replying to you. Submitted all three applications, sponsorship_nomination_visa application, on the 24 April 2013. The case officer communicated with us regarding spon and nom on the 17 May 2013. We answered his questions and supplied more info the following day. Spon and nom were granted on the 28th May 2013 and our visa applications were granted on the 29th May 2013. Seeing as we did not use a migration agent I was very impressed with the Immigration Dept replying to us so quickly.
