Somewhere on this forum I read this
I too hold a Tier 1 GM visa dated 23rd October 2008. I have not travelled on this visa yet. Am I eligible to do the same and get the date changed?Hi!
I had a similar situation when I applied in December 2009. So I wrote an application (on plain paper) to change the date (as in the original application) and submitted it to VFS with my passport. After 5 days they gave me my passport back with the old visa cancelled and new visa with new date.
Let me know if you have any other questions.
Any information would help, please.
