I applied for a tier 4 general student visa. Hours before my biometrics I realized I forgot to put down some countries I visited in Europe last year for travel history. My passport is stamped with these places, and I just completed my biometrics. If I cancel my application now to resubmit, will I have to redo my biometrics? Will this for sure get my visa rejected? UKVIS contact basically doesn't work and I have no answers for anything. My application support center said to call the UK embassy, but I have no idea what to do.
