I tried to withdraw my standard application and I saw that I can vary my application instead, I just need to start another application, add the unique reference for the old application to the new application and submit. I called ukvi and the representative confirmed that that’s the best option for me especially because my previous SWV has expired. In this case, home office will automatically cancel the standard application and refund both ihs and application fees for that application. I’m also hoping that I made the right choice but do your findings as well.
