When entering the US, you are required to show forth a return ticket in order to get it. As a rather spontaneous person, I hate making plans, and would like to leave the US and go home when I feel like (within a couple of weeks of course), instead of having to stick to a ticket ordered weeks in advance.
To overcome this problem, I'm thinking this: I will instead purchase a "flex-ticket" home, which is a little more expensive, but also fully refundable. Which I can show in the airport upon arrival, and then cancel afterwards, giving me the option to purchase a new ticket home when I feel like it.
Is this hacking the system, or would it be OK - I'm in doubt because it seems almost too easy.
