Final answer:
States requesting a national officer to travel for an event usually cover 100% of the expenses. The host state is responsible for the costs associated with the visit. Always refer to specific event guidelines for precise policies.
Step-by-step explanation:
When states requesting a national officer to travel to their state for a conference or speaking arrangement, the state will typically assume responsibility for the entirety of the expenses involved. In the context of political events or governmental affairs, it is common practice for the host state to cover the travel, accommodation, and other related costs, which would be 100 percent of the visit. However, specific policies may vary depending on the organization and the nature of the event, so it's important to refer to the relevant governing body or organization's guidelines for accurate information.
