IMPORTANT: For any business trip, you must have:

– a travel authorization WITH expenses (from the sponsoring organization that will pay for your trip)
– a travel authorization WITHOUT expenses (if your employer is different from the one listed on the travel authorization with expenses)

Example: You are employed by the CNRS. You are going on a business trip funded by an ENS research contract.
You must request an ENS assignment order with expenses and a CNRS assignment order without expenses.
