Thank you in advance for your time taken to answer my question.
First of all, I'd like to mention that I'm a dual nationality holder. (this will help you answer my question)
I was an international student undertaking my studies at the UK, however, I was not in a good place mentally then and that reflected poorly on my academic performance, ultimately leading to my tier 4 visa being curtailed. Note that I had left the UK as soon as I received my curtailment letter. ( I had only one citizenship at that time)
Fast forward 5 years, I am now a dual citizenship holder, and the citizenship I recently obtained allows me to enter the UK as a visitor visa-free, I plan on visiting my brother soon who is currently undertaking his studies there. Will I face problems with immigration control at the airport?
