Final answer:
Asking where someone was born is not illegal in general, but in specific situations, it can be considered discriminatory and against the law.
Step-by-step explanation:
Asking someone where they were born is generally not illegal in itself. However, in certain situations, asking about a person's place of birth could be considered discriminatory and illegal. For example, in the United States, it is against the law for employers to ask job applicants about their place of birth, unless it is required for specific legal reasons such as eligibility to work in the country. This is to prevent hiring discrimination based on national origin.
