Analyze the concept of an "undocumented migrant." Why might someone use the term "illegal immigrant" rather than calling them an undocumented immigrant?

Paper Guidelines
Written papers serve two purposes. Firstly, they are meant to show me you’ve understood and thought about the material we cover in class. Secondly, they practice and develop your ability to express your ideas in clear, rigorous language, and develop your own structured argumentative case – in this sense, writing papers is a learning exercise as much as a test of what you can already do. You should focus your papers on the theories we discuss. While your interpretations are critical, “A” papers do so by using direct textual support, and by analyzing the concepts we discuss. “C” and “D” papers make vague, unsubstantiated claims that are more like editorials.
Your papers should be 4-6 pages long (NOT INCLUDING THE COVER PAGE). Do not take up unnecessary space with long spaces, extreme margins, etc. Formatting guidelines are as follows:
1.12 inch font for ALL TEXT including headers which can be in Bold Type but not bigger than 12 inch font.
2.Times New Roman.
3.1 inch margins all around.
4.Cover page should include name, class, date, and paper title. The total page count DOES NOT include the cover page.
5.You can use the paper idea below for your paper or see me if you prefer to write on an original topic.
For this paper you should analyze the concept of an “undocumented migrant.” Why might someone use the term “illegal immigrant” rather than calling them an undocumented immigrant? Trace the repercussions of such labeling. The paper should accomplish the following goals to receive full credit. Be sure to write in narrative form and not just respond to each bullet point.
1) The term “migrant” should be defined.
2) Different types of migrant could be explored, and the legal status considered.
3) Discuss the background of increased global flows of people and the push and pull factors that might be relevant to an undocumented migrant. (Key concepts might include labor migration, refugee, etc.)
4) Students should reflect on the connotations of the terms “undocumented” vs. “illegal,” how those connotations shape the way people think about the people themselves, and if a person can literally be “illegal.”
5) “A” papers might reflect on the unevenness of flows of people and relate this to inequalities, perhaps considering how undocumented immigration compares with less fettered flows of tourists.
6) The role of the nation-state could also be considered.
