What to consider....

When considering workers who have migrated from Central America, or anywhere in the world for that matter, we must think about why they are here.  They are here because conditions in their own country are poor, they are here to find work and opportunity, our economy has a demand for them, and their economy depends on the income from them. 
So why don't more of them have visas?  The U.S. currantly has a population of nearly 11-12 million undocumented residents.  This shows that it must be to their advantage to be here without documentation rather than applying for visas, green cards, or citizenship.  Being here as an undocumented worker also leaves them unprotected easily taken advantage of.  It is also extremely difficult for them to continue travel across boarders so most undocumented immigrants will go great extended periods of time without seeing their family, children, and friends.  All of these factors cause stress to the lives of these migrants who are only able to find comfort in the population of other immigrants.
I would like the reader of my paper to consider all of these issues and ask why we are alienating certain populations of immigrants and if there is a way to make immigration and documentation more of a fair and equal process.   Immigrants will come to the United States whether they are legally documented or not, so what are we to do in order to protect the population of undocumented residents?
