Mercosur Full Members

The full member states of Mercosur, as Mercosur itself lists them. Bolivia is a full member since 2024, having deposited its instrument of ratification in July of that year under Decision 20/19. Venezuela is a full member whose membership is suspended under article 5 of the Protocolo de Ushuaia - suspended, not associated, which is where we previously filed it. Membership of the bloc is all this group asserts. Whether the Residence Agreement actually reaches a given nationality depends on the destination as much as the origin, and is recorded on each country's own residency-regional-treaty override.

Where it actually bites

Membership is one thing and what a destination does with it is another. These are the countries covered here that treat these nationalities differently, and on which question.

    About this source

    The bloc's own institutional pages, and the only authority on who its member and associated states currently are - which is not the same question as who is party to the Residence Agreement.

    Standing: Reports, establishes nothing

    Cannot be cited for: Cannot be cited for treaty texts. Its document pages are stubs whose download links do not resolve, and its normative database refuses automated readers. Membership is all it establishes; whether an agreement reaches a given nationality in a given country is a matter for that country's own sources.
