Just a quick question, we submitted my application for ILR visa yesterday. And I remember that my manager told me that my contract will be terminated on 22nd of February,(that is when my visa expired)

As i understand I am still eligible to work here eventhough my visa expire in 20 days time and the visa is on process? Can anyone confirm that? And for the company ive been working on, they want me to give a proof saying i am allowed, but i dont know where can i get it?

thanks in advance
