Yes, you can upload documents even after the interview. I’ve also attended my interview on March 19th. Currently, my wife and I are in the process of moving into a new apartment.

you can until the close the case. how did the interview go? anything you heard making you upload ?

I was wondering the same thing but now I got my answer
