How frequently must sponsors undergo licence renewal?

Sponsors are not required to renew their licenses, which means they can maintain their license indefinitely as long as they comply with ongoing regulations. This aspect highlights the structure of licensing in this context, emphasizing that once a sponsor has successfully obtained their license and meets all necessary compliance and operational requirements, they do not face the burden of periodic renewal as often seen in other licensing systems. In contrast, the other choices imply a periodic obligation that does not exist for sponsors, which could burden them with unnecessary administrative tasks if it were required. Overall, the absence of a renewal requirement allows sponsors to focus on their operations without the pressure of looming deadlines for license maintenance.
