Thank you for your reply! Yep called them and they said I can only be offered one week (although I’ve heard if you beg they do it the same day) but go into the office and show them the passport they’ll be able to advise you further. Went to the office they told me they didn’t even realise it until I pointed it out so it’s up to me if I want to take the risk. The issue doesn’t even stop with getting a new passport because I’ll need a renewed OCI which I won’t get in time either.
