people think t many immigrants from China, South America, Europe, and so on makes the USA worse. Is that true

Absolutely not.

Explanation:

America was made from immigrant ideals and values. It doesn't even "disrupt American culture" as America is, and always has been a melting pot of cultures. The people come here to live a better life by working hard and contributing to society are vital to America's success. An issue many people bring up is legality. People who sneak through borders are breaking the law. However, while it is important to document people who cross over (for reasons of trafficking and taxation) the application for green card status is extremely difficult. This leaves refugees stranded in border camps most of the time, especially in countries with lower literacy rates. Does this mean the system needs reform? Or should we, as America strive to help fix the problems in other countries? Overall, immigration is extremely nuanced, but it remains undisputed: immigrants are a good thing.
