The reason they have a 14 day turn around time is because there are potentially 1000's of other cases they are also reviewing and they do them in a first come first serve basis. Asking them to review your case ahead of someone else often does not result in a favorable answer. If you think about it, how would you like it if someone did that to you? If it is not life threatening give them the time they need to the review and not rush through it, possibly missing something and then you not getting the results you want! Good luck!
