you’re missing the point. This is not a 90 day report. This is address registration upon arrival in the country. Everyone has to do this. Even elite visa.
Well, if you catch a fish do you leave the pole on the ground and let the fish swim around, or do you reel it in as quick as possible before it swims away?
honestly I do not know. I did research and could not find any reasonable explanation. Others from the US have stated the same but my UK friends do not have this issue.
