You are a frequent traveler from USA and want to access American sites and programs using your laptop but you face certain difficulties. The reason is that there are many websites restricting geographic access to certain degree. This signifies that you must be physically present in the States or have an USA IP Address. If the server detects that you are a non-local visitor they block you (Now, you are on foreign turf). Therefore, it is sensible to get an US IP address.
