I would highly recommend this service. My partner and I used it as part of our application for the unmarried partner visa. Our application was just approved a few days ago, and I have no doubt that was in large part due to Jason's help throughout the process. Jason provided an exhaustive list of all the things you need to include in the application and how to include them. Rest assured your i's will be dotted and t's will be crossed! Jason also provided some crucial insight and advice over email throughout. Obviously, since the visa application costs so much money, you want to be sure you are giving it your best shot. This packet from Migrate ensured that for us!
