Most commonly "issuing country" and "country for which visa applies" are the same. In your case both should be USA.
When there are two different fields, it must be because some countries have cooperation agreements that allow country A to issue visas on country B's behalf to people who live in a location where A has a consulate but B doesn't.
Perhaps it also allows entering things such as "issuing country" being Germany and "country for which visa applies" being all the Schengen states.
