Still waiting for approval after submitting the requested document by CO

Hello everyone I have very important questions to ask. I need to take crucial decision regarding my application but i am so confused, so i am here to ask if anyone can help. I got invitation for subclass 189 (261312 developer programmer) and I submitted all documents after that but CO contacted on 20th feb for additional document and i submitted that document as well. so my question is:

  1. how much time case officer will take to further approve PR?
  2. Most importantly, I am living in Philippines with my in-laws from last 8-9 months, now my visa is going to expire here as well, so i have to go back to India, so my question is ;

: is that risky to change country of residence again and again : Do I have to update my file again , how it will affect my application . i am actually very scared

Pls help
