Final answer:
The statement is false; persons with dual citizenship can obtain both citizenships by Jus Soli if each country involved grants citizenship based on birthplace. Some countries allow dual citizenship, while others do not, and the laws can vary significantly from one nation to another.
Step-by-step explanation:
The statement "Persons with dual citizenship cannot obtain both citizenships by Jus Soli" is false. Jus Soli is a principle of nationality law by which citizenship is determined by the place of birth. In the case of the United States, the Fourteenth Amendment is based on the concept of jus soli, indicating that any child born on U.S. soil is a citizen of the United States, regardless of their parents' citizenship.
It is possible for a person to have dual citizenship from different countries if each country grants citizenship through jus soli. For example, if someone is born in the United States to Canadian parents, they may have citizenship in both countries if Canada also recognizes jus soli. However, not all countries allow dual citizenship, and the specific laws vary.
Some countries, like Canada, France, Mexico, Australia, and the United Kingdom, permit dual citizenship, whereas others, such as Germany and India, do not. There are unique circumstances in some places as well; for instance, Japan requires individuals holding dual nationality to choose one citizenship upon reaching the age of 20.
