Hi Topman2014

Yes we sent a covering letter along with the supporting letter explaining the situation that my visa is running out. And then again when I applied for my tier 2 I have included separate covering letter giving our sponsorship application number. Hope that helps.

I just want to share my experience. My visa expired on 6th Feb 2014 and my company applied for licence on 4th Feb 2014. I applied for my visa on 5th Feb without cos. I received an email from my caseworker on 19th feb notifying me that he will hold my application until my company receives the licence...
