Hi,
Just to update my status, I got my Tier 1, 3 year visa extension today
26 January 2010: First application made
01 February 2010: Visa Expired
13 February 2010: Application returned back saying invalid application for unsuccessfull payment
16 February 2010: Re sent the same applciation form with entering payment details again
18 February 2010: Payment successfull
26 February 2010: Realised, I did not sent the last 1 month maintenance funds proof (bank statement)
01 March 2010: Contacted the home office and this forum
02 March 2010:Posted the Bank statements with a covering letter
02 March 2010 to 22 March 2010.: Sleep less nights, days with worries, stress and tense
Lesson learnt: Post the application as early as you can, double check and triple check the whole application to make sure the application is made as per the UKBA requirements.
