Dear <Recipient’s Name>,
I am writing to ask about visit the White House on <group or person traveling> Is there a cost involved? Are reservations necessary? Are there security issues I must address?
I would appreciate it if you would have a staff member contact me with this and any other important information. I look forward to seeing the White House.
Thank you very for your time and consideration. Would be looking forward to your response at the earliest.
