A more thorough explanation:

Definition: National domicile refers to a person's permanent home in a particular country, to which they intend to return and remain even if they are currently living elsewhere. It is the place where a person has a settled connection for legal purposes, either because it is their home or because the law has designated it as such.

Examples: If a person is born and raised in the United States and intends to live there permanently, their national domicile is the United States. Similarly, if a person moves to Canada and intends to make it their permanent home, their national domicile becomes Canada.

These examples illustrate that national domicile is determined by a person's intention to make a particular country their permanent home. It is important for legal purposes, such as determining a person's tax obligations or their eligibility for certain benefits.
