I love to travel around the world although I had been abroad only one time. I most want to go to one of the countries is Russia because it is by far the largest country in the world
. We can travel by train. But I think to plan & book an overland journey from London to China or Japan by Trans-Siberian Railway is very cool and exciting.But I am afraid it is not safe to pay cash for buying something.So if I can use my visa card like Russian visa
service, I think it will be convenient. You can try this.
