Which of the following is NOT a requirement for obtaining permanent residency in Canada?

Securing a job offer from a Canadian employer is indeed not a requirement for obtaining permanent residency in Canada. Canada's immigration system includes several pathways for permanent residency that do not necessitate a job offer. For example, individuals can apply through programs like the Express Entry system, which assesses candidates based on a points system considering factors such as age, education, work experience, and language proficiency.

The validity of a passport is essential because it demonstrates an individual's legal identity and ability to travel. Meeting health and security checks is also a critical requirement, as Canada wants to ensure that new entrants do not pose health risks or security threats. Showing proficiency in English or French is important since communication skills can significantly influence one's ability to integrate and succeed in Canadian society.

These requirements are structured to ensure that applicants can contribute positively to the community and the economy, but having a job offer is not mandatory for all immigration pathways, making it the correct choice in this context.
