URGENT HELP: Admin Review Successful. Options now??

Hi guys,

Please review my case and please suggest the options I have in hand.
My case (in a nutshell):

1) Tier-1 application: 29-Mar-09
2) Date of travel in Tier-1 application: 01-Aug-09
3) Tier-1 rejection: 23-Apr-09
4) Admin Review application: 27-Apr-09
5) Admin Review response: 07-Dec-09
6) Admin Review result: Succesful. Points achieved.

When I made the Tier-1 application on 29-Mar-09, I had something working out "employment wise" in the UK. But, due to the Tier-1 rejection in April and the subsequent time taken for the Admin Review, obviously that offer went out of my hands.

The Admin Review response letter has asked me to submit my passport and the tentative date of travel.

Frankly speaking, my professional and personal situation has changed since my application and I can't make an immediate decision to travel to the UK soon.

I would like to know what my options are, if I'm entitled to any special rights.. like a deferral of 3+ months of the date of travel etc.

Thanks a lot for your help everyone!

Regards
