My question has already probably been asked before, but I'm looking for some insight into my specific situation. Some basics on me - I'm a Canadian citizen, am not married and am 23 years old. Two years ago in April 2014 I was denied entry to the UK. I was travelling through Dublin to reach Belfast where I was to stay in a hostel for one month. In exchange for manning the front desk of the hostel for a couple of hours each day, I would be allowed to stay in one of their beds for free. The immigration officer saw this as work, and coupled with the fact that I did not have much money and no ticket to leave, I was denied entry. I was denied entry to the UK, but it all happened in Dublin. I totally understand the reasons for this, it was exceptionally stupid on my part. I have since been granted entry to Ireland twice, but I have not tried to go back to the UK.
Now, I've been accepted to study my Master's degree at King's College London. It would be a dream come true to study there. My plan is to defer for a year so that I can have as much time as possible to sort out my visa and to gather as much money as I can.
My question is: will my student visa be rejected because of this past incident?
