I've read from other forums that they go by the "required documents" date, and for me I think it's true but that's just me.
my attorney only submitted 1 year tax transcript for 2021, so I went ahead and submitted 2020 and 2019 tax transcript and w-2
as far as uploading additional documents I'm planning on uploading our 2022 taxes and 3 most recent paystub when I go for the interview.
