Its a Scam. Don't use it.
This site is sponsored to show top of the list when you search for a specific country visa. it is designed to look as if it is connected to or is the official visa site of that country. However it is not. I was charged $159 for a Rwanda visa (including an additional penalty fee to processing a visa for a UK passport). It was only after paying the fee I did my further checks to find that UK nationals are given a visa free on arrival. I tried to cancel my application with Global Visa Corp but of course they would not accept to refund the fee. I have challenged them on their scam but they are adamant. DO NOT USE THIS "SERVICE"
