Final answer:
A person moving from China to Canada for work is engaging in immigration, which is the act of entering another country to live or work there, as opposed to internal migration which occurs within the same country.
Step-by-step explanation:
When a person moves from China to Canada in search of work, this movement is categorized as immigration. This is because immigration refers specifically to the process of moving to another country, as opposed to interior migration or internal migration, which occurs when people move within the same country. Immigration involves establishing oneself in a new country with the intent of living there permanently or for a substantial period of time. Prominent reasons for international movement like this include seeking employment, better living standards, or economic stability. For instance, China's hukou system can make internal migration challenging, thereby influencing some to seek opportunities abroad. In our particular case, the individual is not simply moving to another location within their home country (internal migration), but is instead crossing international borders to find work in Canada. This clearly falls under the definition of immigration, which is concerned with entering another country to live or work there on a semi-permanent or permanent basis. Labor migration is a larger category that both immigration and internal migration fall under, considering it involves moving for employment purposes regardless of whether the move is within a country or across countries.
