there’s a general rule with this kind of thing…you can’t have too much evidence! Provided it’s all valid and relevant, take it all. Shows you’re prepared and have plenty to show
Dont worry about that. You never know what may be asked so you at least go in this way feeling more confident and prepared. No one will ever be rejected for having too much good evidence
it’s not quite the same, but when I applied for my 10 year green card, the pack that I submitted was over 400 pages long and got approved very quickly (maybe didn’t want to have to read them all!!)
