Country of domicile refers to the country where an individual maintains a permanent home. It is the location that a person considers their permanent home, where they maintain social, economic, and family ties. Legally, it is the address declared in legal documents such as the address used to vote, bank, register vehicles, and pay taxes. It is important for immigration paperwork, tax filings, and other legal proceedings.

A person can only have one country of domicile, even if they live in more than one country throughout the year. It is possible to change ones domicile without changing citizenship. A domicile is different from a residence, which is a location where a person may live part-time or full-time.
