[quote="manci"]You are back in the UK now and presumably working for your present sponsor. If both your sponsor and you want to extend your employment till 30 April 2013 the sponsor has to assign a new CoS to you. An offer letter is not enough and the previous CoS has already been used for the application that was refused.
The work end date in the new CoS will be 30 April 2013 and if your application is successful your new leave to remain will be to 14 May 2013. (14 days after the work end date) You should apply using the form:
http://www.ukba.homeoffice.gov.uk/sitec ... nform1.pdf
(but check if that is still the correct application form at the time when you actually apply)
If you apply from the UK before your present leave expires (30 Jan) your existing leave automatically continues until UKBA make a decision on your application, so you can continue working after 30 Jan.
If you find a new job and new sponsor they will have to assign a CoS to you and then you can apply for a further leave to remain[/quote]
Thanks, Manci.
Yes! I got an new offer letter with new CoS. It seems that I can apply for leave to remain twice (with changing a sponsor). Because I heard that Tier-2 (G) can go upto 5 years and my Tier-2 visa from May-2010, the final two questions are
Is the maximum of my visa extension until Apr-2015?
What shall I do if my future contact period can be beyond Apr-2015?
I appreciate your kindness and help!
