Answer
Yes, a child born outside Uruguay to a Uruguayan parent may have Uruguayan status by descent. But this does not mean that a parent’s passport automatically provides the child with a complete set of documents: citizenship, birth registration, a cédula, and a passport must each be obtained separately.
In such a situation, it is important to distinguish between a natural and a legal citizen of Uruguay. For a child of a ciudadano legal who was born abroad, different interpretations are possible, because in practice, ciudadanía and nacionalidad are often mixed. So a general response without a family chain may be overly broad.
For registration, it is usually necessary to confirm the child’s birth, the identity of both parents, and the Uruguayan status of the parent. If the basis is descent through ancestors, documents from grandparents may be needed. The foreign birth certificate may require an apostille, translation, and entry in the Uruguayan registry.
