Answer:
Option B.
Step-by-step explanation:
Requiring all immigrants to carry official documentation, is the right answer.
Immigration is a term used to describe the worldwide migration of people to a target nation of which they are not citizens to reside or settle there, primarily as permanent inhabitants or naturalized immigrants, or to get jobs as a migrant operator or tentatively as an international worker.
Therefore, if a state or government wants to manage the current immigration policies, it may ask all immigrants to bring official documentation.
