Sir. U made two errioctions
First : u cannot apply for the visa by offer letter , instead EVAL will be needed.
Second: Your uni will not give you second offer letter, in the opposite they will provide a new deferement letter which allows you to fill the gap of offer letter to get EVAL .
That procisely what happened to me when i defered due to delay of EVAL . Good luck
