Just giving some ppl a clue.
They NEVER asked any update or additional files but if you are SURE of what you are sending... i've sent a batch in March-April when Covid happened and it's been added to our case and reviewed by an Officer which has finally said Completed / passed for eligilbility.
Cause when you apply ... usually a year pass before they finally open your case at the VO so.. in this year , some events sure happened and all that could help them decide if that's genuine or not..
So for those in my situation and that are still waiting a response , i would say before getting an interview request cause it's not sufficient,i would recommend to send them a pdf with a Collage (to resume) what happened during that year since you applied.
Trips to visits , gifts sent , communications and all.
Help them to see the relationship is still continuous and valid.
