I had lived in the UK for the last five years on work visas. But I was unsuccessful on my renewal of my last visa application. I did not have an extension to stay in the country as my visa expired during the application and the Home Office held my visa. I left the UK within the 30-day voluntary leave period and my passport was returned back to me at the airport when I checked in for the flight I was flying out of. I plan to go back to the UK to visit friends within the next 3 months. Will I have issues when I get to the UK border? I only plan on visiting the UK for 2-3 weeks and I have a return flight booked.
Would getting a new passport with a new number be better for me?
