USA immigration history is full of draconian and hospitable seasons. Our Statue of Liberty represents the best in our history as Ellis Island welcomed millions willing to brave the journey, go through the vetting and find a new home in a new nation. We have also had horrific seasons of xenophobia and racial injustice, from the suffering of the Irish in the 1840s to the anti-Chinese laws on the West Coast in the 1890s to the anti-Semitism of the 1920s -1940s. Dark chapters indeed. With huge borders with Canada and Mexico and relative economic prosperity from the end of WWII to the 1970s, comprehensive policies were not needed, and many found their way to flourishing.
