I've read that many people are sending in "evidence" ie. life insurance, home insurance, etc with their N-400. Can anyone point me to where you are instructed to do so and what they are asking for? I can't seem to find anything that tells me to send more than the application itself and the payment. Thanks!

You can find a checklist of what is needed for form N-400 here:
