The Brazilian government has announced new restrictions on Asian migrants using Brazil as a way to enter the United States and Canada. This move, starting on Monday, affects those who require visas to remain in Brazil and have used the country as a layover before continuing their journey north. The increasing number of migrants at the airport in Guarulhos, near Sao Paulo, has raised concerns and led to this decision. This comes after an AP investigation found many migrants from India and Vietnam using Brazil as a route to the US.
