The short answer for when to reapply for an entry visa is 6 months. However, your country is one of the nations that are on the Entry Without Visa list, allowing up to a 90-day stay. Your wait time for that, if showing an intent not to have permanent stay, is only a matter of weeks. You have only to complete the I-94A application form online, after booking your return flight, but the form must be completed no less than 72 hours before arrival at a U.S. port of entry. Best to you.
