I changed my name recently (First and last due to simply disliking my birthname) and received my new passport.
I visited the USA last year in December with my old passport and old name, do I need to tell them that I've changed it?
I've already applied and been approved for my new Esta.
Oh! I also don't use my old name for anything. I only use my new name (The one on my new passport)
So in short my question is, does/will it matter?
