You make some really good points, but I have some experience in this area. My parents are both immigrants, and I’m the first generation American in my whole family. My parents moved to the U.S. from India, and have lived here for nearly 20 years. Throughout the years they say they’ve noticed a lot of change in the country. Earlier, 20 years ago, it was difficult to find people from other countries. Especially those from India. But now you see immigrants everywhere and Indians a few times a day. They say they’ve noticed a huge cultural change and political view on immigrants since they got here. They talk about how immigrants bring in aid for the economy by filling things up like American jobs. And also spreading different beliefs and cultures across the nation. If suddenly immigrants weren’t allowed or just disappeared in the country. We would automatically take a toll to our economy because many immigrants supply it. We would also lose our diversity which is extremely important int this day and age. Bottomline is immigrants are important, and more are coming to help shape our country, but to make it much better. After all, every American has great grandpas or grandmas who were immigrants. Therefore nearly the whole population of the nation are all decenedtns of immigrants from Asia, Europe, and other parts of the world.

I liked most of the points you were making. Immigration is a scary thing most of my family being immigrants could agree that it is not easy going from their native country mexico to America this mainly being because of the language barrier making it harder for them to take advantage of any job opportunities that require them to be able to fluently speak english and causing them to get a low class job. This being a factor you might ask why did they migrate then it was because of the benefits of living in america such as the health care system and other opportunities such as education for their children so the adult immigrant population may not have the best benefits but putting that aside they tend to migrate to allow their children the opportunity to have more later in life. This being one of the many benefits of immigrant migration that is highlighted in an article by edgar cohen whose opinion on the matter you might find interesting:
