Entry Requirements, Visas, and Documentation in Brazil: what actually matters to know

Short answer
Carry birth certificates to prove familial relationships when traveling with children of different surnames and verify specific requirements with local immigration authorities. Russian citizens must exclusively use their Russian passport for border crossings involving Russia, while travelers crossing between Brazil and Argentina should provide proof of exit, such as a refundable flight ticket.

From real experience

When crossing borders with children who have different surnames from a parent, it is advisable to carry official documentation that proves the familial relationship.
While specific requirements can vary by country and border control, carrying birth certificates (potentially with certified translations) is a common recommendation. It is best to verify the exact documentation needed with the relevant immigration authorities of both the departure and destination countries prior to travel.
