The United States: Melting Pot or Salad Bowl?
The United States counts its population every 10 years, and each census reveals that the racial and ethnic mix is changing dramatically. By the year 2050, the “average” person in the United States will not be of European descent. By 2050 the majority of U.S. residents will trace their ancestry back to Africa, Asia, Central America, South America,the Hispanic world, the Pacific Islands, and the Middle East. The United States used to be a microcosm of European nationalities, but now it is a microcosm of the world. The United States is no longer considered a “melting pot” society by many of its residents; instead, many people prefer the term “salad bowl.” They use this term to describe U.S. society because it will soon be predominantly of non-European descent. “Melting pot” implies that the different ethnic groups blend together into one homogeneous mixture. "Salad bowl” implies that nationalities, like the ingredients in a mixed green garden salad, retain their cultural identities.
Earlier generations of immigrants believed that they had to learn English quickly. Not only did immigrants need to learn English to survive but also to become successful. Recently, many communites in the United States do not feel the same need, because there are many places in the United States you can work, shop, get medical care, marry, divorce, and die without knowing English. For example, people who live in Chinatown in San Francisco and in New York do not need to speak English. In Los Angeles, which has many immigrants from Vietnam and Mexico, do not need to speak English to live comfortably. In addition, many immigrant groups want their children to know their own culture. Many Hispanics, for instance, want their children to learn both English and Spanish in school. They are fighting for the right to have bilingual education in many communities, of which they are the majority.

The United States: Melting Pot or Salad Bowl?
The United States counts its population every 10 years, and each successive census reveals that the racial and ethnic mix is changing dramatically. By the year 2050, the “average” person in the United States will not be descended from Europeans, but instead, the majority of U.S. residents will trace their ancestry to Africa, Asia, the Hispanic world, the Pacific Islands, and/or the Middle East. Once/In the past, the United States was a microcosm of European nationalities, however, tomorrow/in the future, it will be a microcosm of the world. The United States is no longer considered a “melting pot” society by many of its residents; instead, many people prefer the term “salad bowl.” They use this term to describe a U.S. society, so it  which will soon be predominantly non-white/caucasian/anglo-saxon. The term “Melting pot” [<em>there seems to be no set spelling for "Melting Pot/melting pot/Melting pot, etc., as well as "Salad Bowl," but whichever spelling you decide to use, make it consistent throughout your essay...]</em> implies that the different ethnic groups blend together into one homogeneous mixture, whereas the term “salad bowl” implies that nationalities, much like the separate ingredients in a mixed green salad, retain their separate cultural identities.
Earlier generations of immigrants believed that they had to learn English quickly, not only to survive, but also to success succeed/be successful. Now, however, that belief no longer exists as strongly many places in the United States do not feel the same need, because there are many places in the United States where you can work, shop, get medical care, marry, divorce, and even die, all without knowing the English language. For example, there are many people who live in Chinatowns in San Francisco and New York who do not really need to speak a single word of English, and similarly, Los Angeles has many Vietnamese and Mexican immigrants and immigrants from Mexico, and they, too, do not really need to speak any English neither. In addition, many immigrant groups want their children to know and/or retain their own culture(s). Many Hispanics, for instance, want their children to learn both English and Spanish in school. They are also fighting for the right to have bilingual education taught in many those communities, in which they are in /or, ...in which they comprise.., or, .in which they make up..] the majority.

An excellent composition! It "flowed" and your statements were backed up by facts and/or good examples! Great job! As to if you essay has "Fragment, Run-on, Comma Splice, Choppy, or Stringy," I'll leave that to be pointed out by my fellow English speakers <em>who actually paid attention in class</em> to the finer points of our fair language!  LOL!

You had a couple commas that aren't needed and one place where there should have been a comma. Two words were mispelled or - more likely - just the wrong word used.

Overall, this demonstrates a very good mastery of the English language. Most college graduates don't have this degree of proficiency in English. In fact, until I proofread it closely, I suspected a copy-and-paste from a previously published work. You have my apologies and congratulations.
