Yes, my dad.
They did not request for proof of residence. But they requested for document confirming the name of my Dad and they didn't accept passport. They only accepted statement from a US bank, credit card, utility bill or US govt doc. (I think it could be because my dad's name is a bit unusual).
So essentially no different to the requirements for proof of residence.
I think its pretty random and they may/may not ask depending on whether the system flags anything. (My dad's name only contains 2 letters for first name and last name).
I didn't need to provide any docs when I applied back in 2020.
