Through evangelism, the PCA is committed to reaching the multitudes in North America for Jesus Christ, and Brazilian people comprise a key segment of this great number. A growing population of Brazilians has been immigrating to the US in recent years. At first concentrated in the Northeastern US, this vibrant community has spread along the Atlantic Coast of the United States. Estimates indicate that South Florida houses a larger group, followed by Greater Boston and New York Metropolitan areas.

Today, there are twelve churches and missions in the PCA that hold regular Sunday services in the Portuguese language.
