Earlier this year I received a Business Visitor visa for the UK which is valid until 15 Nov, 2017. I went there for a business meeting that was successful and therefore I've received a Diplomatic Visa for the UK today. The start date for my diplomatic visa is 25 Sep, 2017. MY Employer made the same (25 Sep) my start day at work.
My Question is if I can enter the UK on my initial business visa on the 20th of Sep so I can sort out my accommodation etc before I begin work on the 26th at my office?
