Introduction
Dual citizenship or holding citizenship of more than one country makes it possible for a person to be legally a citizen of two countries simultaneously. It is a longed-for thing by many due to greater chances of traveling, business opportunities, and family factors.
However, the regulations differ from one country to another. While some countries completely permit dual citizenship, others are restricting it, and some forbid it entirely.

Understanding Dual Citizenship

1. What Is Dual Citizenship?
Dual citizenship refers to a situation where one is legally considered a citizen of two nations. It permits a person to possess two passports and benefit from the right to vote, reside, and work in either country.

2. How the U.S. Recognizes Dual Citizenship

3. International View of Dual Citizenship
Nations deal with dual citizenship differently:
- Some completely support dual nationality without limitations.
- Some permit it only in special circumstances (i.e., through marriage or descent).
