We used the DIY application package for our successful fiance visa application which was probably the best decision we made in the application process. Our case was fairly straightforward, but because the application process itself is so complicated, using the packet and its fantastic checklist was key. We also emailed a few questions that were specific to our financial evidence and heard back from Migrate really quickly with clear answers. If any of my friends were to go through the application process, my two biggest pieces of advice would be 1. use reddit/UKvisas and 2. use the Migrate DIY pack!
