I will grant you, the letters are usually misleading about how much you "need" the documents. But aside from that, I have hard time tagging it as a scam.
You can pay a guy to mow your lawn, but just because you could do it yourself for free doesn't make him a scammer for charging you. Nor for suggesting your lawn needs to be mowed.
Yeah, but the guy cutting your lawn doesn't imply you can't do it yourself or he is giving you any special service unavailable doing it yourself.
