Administrative Review (Mistake on the length of stay)

Hi all

I hope somebody can help with this.

I have recently got my visa and there is an error on my length of stay (by three and half months), so I plan to apply for an administrative review. My question is, when I send off my application, will the current leave I have been granted still be valid until a decision has been made or will it be my previous leave (superseded by my current leave), which is still yet to expire?. I understand for refusals, leave is automatically extended under section 3c until a decision has been made. As this not a refusal and just a mistake, how does it work?

Your Tier 4 leave has been granted and it is valid and current. It has superseded any previous leave. Requesting correction of an error via an AR does not cancel your leave, it just corrects the error.

The international student adviser at your university can advise.

Oh Ok thanks a lot
