Final answer:
The requirement to report foreign travel is generally true for certain official groups, not for the public. The Iroquois Confederacy had members who took sides in the Revolutionary War, and the Treaty of Paris granted the U.S. land east of the Mississippi. The Louisiana Purchase indeed doubled the U.S. territory.
Step-by-step explanation:
The requirement to report all foreign travel, including day trips to Canada and Mexico, is generally true for certain groups such as military personnel, some government employees, and individuals with high-security clearances. For the general public, this is not a standard requirement, although it is advisable to be aware of any specific guidelines pertaining to international travel from the relevant authorities.
