Which of the following describes a passenger traveling from one country to another for settlement?

The term that best describes a passenger traveling from one country to another for settlement is "Emigrant." An emigrant is specifically someone who leaves their own country to settle permanently in another country. This reflects an intention to establish a long-term residence rather than a temporary visit.

Understanding this concept is crucial in the context of international travel and immigration patterns. Unlike a deportee, who is forcibly removed from a country, or frequent travelers who might travel often for business or leisure without settling down, emigrants make a conscious choice to relocate and start anew in a different country. Additionally, involuntary passengers typically refer to individuals who cannot proceed on their journey due to circumstances beyond their control, which does not apply to someone moving for settlement. Therefore, the classification of emigration accurately captures the essence of the described activity and purpose of travel.
