Beware of the brave new world of reciprocity.

If the U.S. is charging foreign visitors a visa fee, don’t be surprised to be charged one when you visit that country. The same thing applies to airline tickets. The U.S. often wants to see proof of a confirmed round trip ticket for visitors.

Now, many foreign countries require proof of a return ticket before they will allow you to enter. And what about financial responsibility?

While the U.S. is beginning to demand deposits of up to 15,000 for foreigners to post to guarantee they’ll return home when their visa expires, reciprocity is starting. Now, officials in Bali want tourists to show three months of bank statements before they’ll let you enter.
