Subject Line: Request to Submit Tour Request of the White House

Dear Canadian Embassy,

I am writing to request your assistance in submitting a tour request of the White House for myself and my girlfriend, Fiona Owens. Fiona is a citizen of Maryland and she is also interested in having a tour of the White House.

The date of our visit will be from April 25th to April 27th and I am available at any time during this period. However, if it’s possible, we would appreciate if we could have a tour planned for April 26th together at the same time.

Your prompt support in this regard will be highly appreciated.

Thank you for your time and consideration.

Sincerely, [Your Name]
