It's a bit of a strange (stupid) case: I was granted an entry clearance for a UK Tier 1 visa (applied from South Africa). For numerous reasons (some medical), I couldn't travel before the "Valid until" date. But I didn't pay sufficient attention to the date or make any attempts to change it.
Given that I've already been granted a visa that was supposed to last a year, will I have to start the entire process again? Or could I just apply for entry? As I'm writing this, that second option seems highly unlikely but figured I'd ask. Any guidance would be appreciated.
