Silver premium package vfs global

Hello All,

I am submitting my application for the Tier 5 GAE UK visa as a US citizen (submitted in US) and will be attending my premium service appointment in NY.

I am trying to pay for the remaining fee package but not sure which one to get. I will only be in NY for about 4 days and am wondering if I purchase the Silver premium package it will be processed in time or do I need to purchase the Gold package??? I have checked everywhere to see the processing times for the silver package but can't seem to find it. The gold states that it will be processed in 24 hours.

Can anyone advise on this? or can I call VFS Global and ask them?

Thanks!!!
