First post here, sorry if there's any mistakes.
I'm an American in the UK on a Tier 4 student visa, but my partner (British citizen) and I want to get a civil partnership. However, because of COVID (ugh) we can't get an appointment to give notice our our local registry office until 22 Sept, so our ceremony would be in late October at the earliest. But my visa ends 30 Sept. I've already completed most of the application form and collected all the other documents. I'm just wondering if it's worth sending the application before we're officially married or if there's another route I should take. I'm also concerned about if any of the documents are time-sensitive, if giving notice so late would mess everything up.
Any advice is much appreciated, thanks everyone!
