No, because Mexican, Brazilian, Uruguayan, American, Peruvian, and Canadian are legitimate nationalities. There is no "Latin American" passport or ID. There is nothing federal or legal about the term "Latin American". The geographical region currently known as Latin America is not invulnerable to renaming. There is no substance to the term "Latin America", it can be easily renamed. Nations, on the other hand, are not as vulnerable to be renamed. If you want to be more general, then there are more appropriate labels like South America, Central America, North America, and Caribbean/West Indian.
