Hi, please advise, I applied for a trv on December 1 2022, I was sent a procedural fairness letter on February 8 2023 asking me to explain my us visa refusal that wasn’t mentioned on my application, I responded and waited, yesterday I was emailed with a final decision notice, I was notified of a 5years ban for I admissibility by misrepresentation, I am so numb, i used a travel agency and was never asked about the us visa, and I explained all that in my letter but was still banned, what do I do now??? Please advise me.
