I'm sure this has been asked before, but has anyone here sent additional supporting documents to Singapore? I'm thinking of sending extra chat logs, copies of plane tickets, etc., as further proof that my wife and I are constantly in touch and that I've visited her again since we applied. Her ECAS is still stuck at "Application Received", and we haven't received any other word. Would there be any problem in submitting some extra evidence at this point? If not, is there a particular procedure for sending it over?
