Regardless on what you do the money is always non refundable. Even if you sent what they wanted and they still decided to reject or cancel your visa it would still be non refundable ..
Anonymous participant I understand and would be worried too lol but if anything…. They would just say application canceled… and have you start again? I used a visa agency though and they helped me and she suggested I write a letter explaining why I don’t have my 2024 taxes yet and when they uploaded it the visa was approved in less than 2 hours
