correct, but you can’t call land lines. It’s only good if the number you’re calling has an Internet connection that’s what was so nice about Skype. You could call land lines or mobile numbers.
If you do decide to file the E visa form, you must first find out which Thsi embassy or consulate has jurisdiction over the state that you live in. For instance, when I filed for my retirement visa, I lived in Texas, so I had to apply to the embassy in Washington DC. They will ask you that information on the first page of the E visa application. They also have consulates in New York, Chicago, Los Angeles, and New Orleans.
