Very positive experience with Korvia. They really helped and guided me through every stage of the process. I would highly recommend them!
The process of applying for a Korean visa is long and tedious with many steps. Korvia help break it down through webinars and emails to make each stage easier. I don't think I would have completed it by myself.
The pre-interview webinars were extremely helpful too, going through interview questions and setting up your camera, giving tips on clothes to wear and background.
