Looking for clarity on the following. I have been granted a Tier 1 Visa for exceptional talent. This gives me 5 years and 4 months. Upon sending my application in for processing I indicated that my intended date of arrival was the 3rd of November 2016. Since submitting this, I have been offered work in my field and will need to arrive on the the 5th of October 2016. This will see me entering 4 weeks earlier than intended. Should I have a letter to take with me supporting this reason for earlier entry? I was given endorsement from the Arts Council of England in August of this year and am awaiting my physical visa and passport back within the next few days. Not sure where I stand on this matter with entering earlier?
