There are two "beliefs" here in this forum. I am a strong proponent of "do not submit anything you weren't asked for because it will only raise questions". There are poeple, though, who think it is OK or even good to submit additional information.If I apply without passport, I will definitely be providing a letter explaining why and I have my expired PR card since Dec2016 and my other passport (the one before my Dec2016 passport) because it was valid until 2013 so it counts in the 5 years they will be looking at. I can also present docs that can prove that I was in CA for the past 3 years such as copies of my pay stubs from Nov 2015 since I came back up to whenever I will submit my application in Nov2018. Credit card statements, what else, I mean anything that can prove that I was here straight esp during that gap from May2018 to Nov2018..
Do you think I should do that - provide unasked docs?
In short: I would say "definitely no", but be aware that a decent number of forum members wouldn't agree with me.
