What does the Catholic Church say in regards to immigration? The answer is in the Catechism.

“The more prosperous nations are obliged, to the extent they are able, to welcome the foreigner in search of the security and the means of livelihood which he cannot find in his country of origin. Public authorities should see to it that the natural right is respected that places a guest under the protection of those who receive him” (CCC 2241).

This policy is neither Republican nor Democrat because the Church isn’t aligned to a political party. It’s aligned to the moral principles of the gospel.
