Corvette is correct on that one. In a general given basis sites that are sent off to Visa for approval can come back as quickly as 3-5 days. However, this does not guarantee that every account sent to Visa will be processed in the same amount of time. The actual time frame itself account approval from Visa is 7 -21 business days.
Hope that helps clear up some confusion.
