I applied for a B1 visa and attended the visa interview at the London site on 02/07/2019. It was approved by the officer and he said I should receive it in a few working days. However, the photo I uploaded to the DS160 form is a few years old (same as my UK passport) which I have just realized is not suitable but the hard copy photo that I supplied them was taken a few days ago which is. The visa officers did not raise this issue at the interview so I would just like to inform them about this. Hence, I have emailed them but will this make any difference? I also submitted the updated photo along with the application that is 2x2inches so do you think they will realise this and use the new photo or do I need to do something?
