They left some of my relatives in Singapore flying from Kathmandu saying that they had no transit visa in Honkong. None talked about the need of the visa while in Kathmandu. Suddenly, they say that you cannot fly at the time to board another plane that had transit in Honkong. They needed to buy much more expensive another flight ticket to get to the USA. All their family and travelers were in a very difficult situation going thru all the hassles .
