Some people say that it is possible. I also heard that the Embassy will have to invalidate the Tier 4 visa. If they do invalidate it, does the British embassy place a cancelled stamp on the Tier 4 visa or do they cross a line through it? The reason why i am asking it that I currently hold Tier 4 visa that is valid until next four months, however, i finished my course in the UK and am aware that my circumstances have changed and as such I have to apply for a visit visa if i want to visit the UK soonest.
My second question is regarding evidence proving family ties. I currently earn a living from the UAE and i am resident here. However, I am a Ugandan national and also single. How then will I prove family ties if I am resident in a different country other than that where my extended family is? Of course I can prove that I will return because of the economic ties to the UAE, but how can i prove family ties to UAE, since my extended family lives in a different country?
