I am going to be in UK for six weeks for research purposes, doing my PhD currently. I have a friend's wedding in France I'd really like to go so need a visa for a couple of days.
How hard it is? I am a Turkish citizen, and will have a student visa from the University of Liverpool. I know it is a short-term visa, but for a wedding and in case of an invitation letter and so on, do you think they will push it too hard?
