Hi, are you Pinoy too?
an "implied status" is when you apply for a work permit extension before your current work permit expires. Your question is a bit confusing in details. You applied for a work permit extension last Dec 2011 without any results yet, right? How come you have a work permit that will expire by Sept 2012?
Work Permit application by paper will only take 24 days to process for the same employer while online application only takes 17 days. You can call the toll free number at the back of your work permit. They will ask for the client ID number written on your work permit as well as the year of your birth. They would have a decision for you by now... IF you did pass an application last Dec 2011.
send me a private message if you still have questions coz I'm a bit confused with the details you gave. I might not be able to follow this thread.
