I want assistance analyzing all possible immigration issues, problems, disadvantages versus advantages and benefits!
First, what does immigration mean? What's the difference between a legal and illegal immigrant, aren't both humans who are looking for a better life?
What does mean an illegal alien/illegal immigrant? What makes someone an illegal alien?
How could illegal immigration problems be solved?
What are costs and benefit of immigration as incentive/disincentive for labor movement?
How important is an immigration reform/bill?
Please include examples, charts/graphs, and all references and the sources.
