My school are currently confirming with the embassy some details regarding documents but they will provide me with a letter to the relevant embassy, whichever one they and I decide on.
For the satisfaction of those who recall my previous post: I had an unusual situation whereby my first non B visa was granted while I was on my flight to Thailand from the UK. I didn't know it was granted as I had no Internet access so entered on what I thought was a tourist visa exemption which was stamped into my passport as such (45 days) but the computer system was updated to use my Non B visa unbeknownst to me. Hence the new non B visa application.
