Hi Mrs H welocme to the forum there is a lot of good advice here from the members so stick around and any concerns you have just ask, we are a friendly bunch here.
As to your question there does seem to be a backlog of visa decisions maybe because of new rules brought in from July 9 2012, I have seen here typical visa decisions taking around 8 weeks or more at the moment so just be positive I am sure you will get some good news soon god bless.
