I first visited the UK from June till August 2016 . Then I received a tier 4 visa for 9 months and stayed in the UK from September till April 2017 . I came back to the UK with a short course stamp from September 2017 -> December 2017 and back to finish the short course from January 2018 -> March 2018. The last time I entered I was stopped and interviewed and it was a bit of a complex situation but they didn’t get me into any detention and they let me into the UK however I’m sure they’ve got something against me.
All of that happened a year and a half ago. I don’t need a visa to enter the UK. Now if I apply for an entry clearance will I get a rejection?
