I apologize for the thread topic name, I have no idea how that happened. I guess I copy-pasted something and didn't even take a look at it.
Thank you for the replies, but I have a follow-up question. So if I just suddenly start using a middle name, is it still going to be legal? I mean like putting it on papers. Plus I don't have it in my passport and if I put it on some kind of paper and then I'm being asked to show my ID or whatever and turns out that I don't really have a middle name or is it not a big deal?
