DS 260 question about addresses

[pradgnya]

Hello,

I am a US Citizen and applied GC for parents by CP. I have to fill DS 260 form. It needs addresses of places where my parents lived since they turned 16 years. They are 80+ so all the old places they lived might not even exist. Do they need to provide proof of places they lived too?

 

Please help.

 

Thanks for all the help in advance.
