Hello Loki123,
I'd like to take few minutes to scribble few thoughts that would make you understand small things we usually don't pay attention on. Your application went IN PROCESS on July 20, 2015 and around that time someone took your file and set eyes on it. I want to use a very crazy example just to pass this message across maybe for the last time. lol
On August 20,2015 your file was put on someone's desk in Manila. This person began to ask your file a series of questions and your file was able to answer most of the questions expect why Appendix A was not properly filled. Based on your information you just provided on the thread I see one thing. There was an additional document request for sure, however if you observe carefully the officer did not have any problem with your file. He or she did not request additional supporting documents but it was a routine PPR. They did not ask for photos, emails, phone bills, boarding passes. Anytime these things are requested from a VO, it is a clear that the officer does not get enough satisfactory answers from an application. I don't see anything to be frustrated about. If you were to order your GCMS notes right now, you will see eligibility as recommend pass. That additional request was a routine PPR since Manila likes to request it at the early stage of visa processing. Appendix A request is addition document but it does not raise my eyebrows at all because you will just fill it properly and send it back. So Loki123 you need to chill out my friend lol. To sum up, I have a positive feeling that your file is heading in the right direction. I guess you need eagle's eyes to be able to see in the past, present and future lol. I was just kidding my friend. I need you to read this post with a big smile on your lips and most of all relax.
Notice: Eagle333 is not an immigration officer, cannot be 100% right of how your file is being progressed at your visa office. All he needs is more information from your application then he will guide you with advices.
Good luck
