Do Brazil passport holders need a visa to visit MN?

Brazilian ordinary passport holders do NOT need a visa for Mongolia. Under a permanent bilateral visa-waiver agreement (effective 21 September 2015), Brazilian citizens may enter visa-free and stay up to 90 days for tourism or short visits. Brazil and Mongolia maintain a permanent bilateral visa-exemption agreement, in force since 21 September 2015, that covers all Brazilian passport types (including ordinary passports). Under this agreement, Brazilian citizens can travel to Mongolia for tourism, business or short visits without obtaining a visa in advance and stay for up to 90 days. This is separate from, and more generous than, Mongolia's temporary 30-day visa-exemption program for 34 countries (which runs through end-2026 and applies to nationalities that lack a bilateral agreement). No eVisa, visa-on-arrival, or pre-travel authorization is required for the visa-free stay. Travelers must hold a passport valid for at least 6 months from the date of arrival and should carry proof of onward/return travel and sufficient funds. Anyone intending to stay in Mongolia longer than 30 days must register with the Mongolia Immigration Agency in Ulaanbaatar within the first 7 days of arrival; for stays under 30 days no registration is needed. Mongolia is not in the Schengen area, so the Schengen 90/180 rule and ETIAS do not apply.
