"Residency in Brazil for parents of a Brazilian baby" refers to the legal authorization for foreign parents to live in Brazil on the basis of having a child who is a Brazilian citizen by birth. When a child is born in Brazil, that child is automatically a Brazilian citizen (due to Brazil’s jus soli citizenship law). To keep the family together and ensure the child can be raised in Brazil with their parents, Brazilian immigration law provides a pathway for the foreign mother and/or father to obtain residency status. This is essentially a family-based immigration benefit often categorized as a "family reunification visa" or permanent residence through family unity.
