I used to hold a Tier 4 student visa and had it terminated recently. Before my visa was terminated due to being withdrawn from my studies, I attempted to appeal the decision and was advised to return home as the appeal would have taken months. It did, and it failed. I had to return to pack and ship all my belongings. Flying back, I was detained for 11 hours, and after the interview only given temporary entry as a person liable to be detained. They took my passport, and cut my BRP which I had planned on keeping for sentimental reasons.
The major problem seemed to be the fact that I decided to stay for 43 days on my latest visit. I am a non-visa national so I assumed I would be allowed temporary entry for up to 3 months. But the IO told me I only have 14 days to pack everything and leave.
Two weeks was not really enough time. I had planned on applying for a visitor's visa and re-entering at a later date. However, recent events have required that I return as soon as possible and I won't have time to apply for an entry clearance.
How can I prove to the IO that I am a genuine visitor and receive a leave to enter the UK?
