It depends on the purpose of the trip. If we travel to a chapter, the chapter pays for room/board and IHQ pays for the travel. For training of VST, it's paid by IHQ but often in the form of a grant from the Foundation. It's fairly complex but to get reimbursed for anything the visit has to be approved in advance, reports have to be completed afterward and you have to have receipts for everything.
