If I could give Migrate.org.uk more stars, I would. I have used their DIY pack for both visa extensions, with this most recent one receiving a decision in just 4 days! Not only do they have abundant free resources, which they keep up to date with the most recent guidelines, their paid service DIY pack takes away all guesswork and makes the application process SO easy. I also had a few questions concerning my husband's employment, and Jason always replied within a couple hours. I will always highly recommend Migrate.org.uk to anyone who needs assistance with their visas and can't thank them enough for making this process so easy!
