In this video I summarize a philosophical argument (from Kit Wellman) that nations have the right to restrict immigration in virtually any way they choose.
My opinion on this topic is in line with the Catholic Church: 2241 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. Political authorities, for the sake of the common good for which they are responsible, may make the exercise of the right to immigrate subject to various juridical conditions, especially with regard to the immigrants' duties toward their country of adoption. Immigrants are obliged to respect with gratitude the material and spiritual heritage of the country that receives them, to obey its laws and to assist in carrying civic burdens. (Catechism of the Catholic Church) I believe people have a right to migrate, especially those who are less fortunate, live in a country that is currently at war, cannot find enough resources where they live. They have the dignity of human beings and it's immoral to deny them a chance of better existence for no good reason. Of course, they have to obey law of the foreign country, some regulations are necessary, regarding safety of the citizens.
