In order to guarantee humanitarian assistance to Venezuelan refugees and migrants in Roraima, Venezuela's main gateway to Brazil, the federal government created Operation Welcome in 2018.

A large humanitarian task force executed and coordinated by the federal government with the support of federal entities, UN agencies, international organisations, civil society organisations and private entities, totalling more than 100 partners, the Operation offers emergency assistance to Venezuelan refugees and migrants entering Brazil via the border with Roraima.
