You can call them periodically, but in my case they told me that they were processing photos as of some date and couldn't give any information regarding my application or photos.Yes the date on the new one is Feb 12th, so I need to do it again I believe.
Any Idea on how to track once we resent the photos i.e after the photos are delivered to the PR center..
I think this forum is a good way to get an estimate.
