Hey everyone

Dates :
Biometrics, Document scanning and Interview: 5/09/2017

Email Received: 6/09/2017
email received saying Your online application has been received at the UK Decision Making Centre. Your application is currently being prepared for consideration by an Entry Clearance Officer.

I also have approved request of late arrival from university that is 25th September but I forgot to attach that email into my visa documents and My CAS Letter mentions start date of 12/09/2017

Will it affect the decision?
Also, let me know your timeline of visa decision
