I applied for a visitor visa on behalf of my nephew, who's in Italy. This was refused as it states he did not disclose the fact he already had an application rejected. I thought the question meant had he applied from Italy before, so ticked no. When my nephew pointed out that he had applied for a visa when he was in Pakistan, I stupidly told him that of course the home office would be aware of this and not to worry. If they queried then we would clarify. They didn't query but outright rejected his application and as they thought he was trying to deceive them, he's had a ban put on for 10 years. It seems harsh for something that was a) my fault and b) a misleading question.
I can understand if we had changed his details then he could be accused of deception, but everything else was correct. What can I do, if anything? I feel so guilty that he will suffer from my stupidity.
