I applied for a UK direct airside visa at New York VFS on 17th Oct 2018, as I am flying from San Diego to India via London. It is 30 Nov now, and I still didn't get back my passport. My flight is on 5th Dec. I cannot miss the date, as I have booked another connecting flight, as well my appointment in India to stamp the US visa. What are the options available for me? Any help/suggestion will be appreciated.
