A more thorough explanation:

Definition: A transient foreigner is someone who visits a country but does not plan to stay there permanently.

Example 1: A tourist from Japan who visits the United States for two weeks is a transient foreigner.

Example 2: An international student who comes to study in Canada for a year is not a transient foreigner because they plan to stay for a longer period of time.

The examples illustrate the definition by showing that a transient foreigner is someone who is only in a country for a short period of time and does not intend to make it their permanent home.
