Nowadays, important databases covering passports and travel history are effectively linked. So all your travel history along with valid/expired visas and their respective numbers will eventually be seen by them anyways, even if you didn't upload expired passports/expired visas etc etc
Ok this is important, so what I understand is if my 10 year Valid Amerikan visa is in an expired passport I should upload that as well? I thought they were talking about the valid passports, I have 6 passports for gods sake
I think it clearly states the passport you intend for travel and use, hence an expired passport is not usable or valid. Therefore it makes sense that only visas and stamps within your valid passport that you will use for travel and this application.
