Complex challenges arise when our neighbor happens to be an immigrant. Ideally, unnecessary migration ought to be avoided; this entails creating in countries of origin the conditions needed for a dignified life and integral development. Yet until substantial progress is made in achieving this goal, we are obliged to respect the right of all individuals to find a place that meets their basic needs and those of their families, and where they can find personal fulfillment. Our response to the arrival of migrating persons can be summarized by four words: welcome, protect, promote and integrate.
