Hi guys,
I just want to share my experience to you all, for those who wants to delay their travel in UK (on Spouse visa).
I phoned the British embassy and made enquiries, I was asked to fax a letter stating my reason for delaying my travel.
After 2 days I've got a call from them asking me to go to British Embassy in McKinley and they told me they need to ammend my visa( got it the same day! ). The validity of my previous visa was 16/09/2009- 16/12/2011 now that it's ammended the validity is 05/12/2009-05/03/2012! Great isn't it!!?
Problem solved! Hope this will help!
