Can someone help me out. Someone filled a United Kingdom visit visa online application form for me. He didn't confirm from me if I was refused visa by any country and he put No. He just submitted the form last night. As I was going through the form he sent I saw No. What can I do since the form has been submitted. I need to state that I was refused a United States visa in 2015. Can I write it in the cover letter that I failed to include it. Or what do I advice I do to rectify the mistake. Am so worried right now.
Withdraw your visa application and apply again, this time with the right details.
Do not attempt to correct this as part of the cover letter etc - cover letters can get overlooked, separated from your application, misunderstood and so on. Withdraw your application before its considered.
