Sending additional documents

Hi guys,

I am praying and hoping that someone has a response to this.

I submitted my application for a tier 2 visa yesterday and realised I was supposed to include a printed copy of my online application and certificate of sponsorship. I am not sure how I missed this out but since my reference number was on the online application it seemed fine.

Luckily enough my sons appointment is on a different date...will it help if I add this documents to his? Are the documents reviewed side by side?

Please anyone have any advise. I want to ask at the vfs when I go with my son. I also want to call my sponsor and the UKVI if I can
Ps I was sent a reference number after my application
