Nope, opposite.
Just give the information they need.
Burocracies work very simple: they want to file exactly X pages of paper. Not X + 3.
For example if they want a copy of your arrival card (no longer necessary) and a copy of your entry stamp: put it on two pieces of paper, not on the same one.
Because the first thing any officer is doing is: counting the copies you gave him/her and glancing over them.
One paper to much, one paper to less: and s/he starts investigating.
There is no reason to give copies of 25 bank accounts when they only want to see ONE.
