These two essays state the rights that the Mexicans have in the US and what issues could arise from them. However, although each writer spoke about these topics, they each view it through a different lens.
You need to clarify whom you mean. Does "Mexicans" mean Mexican-Americans? Mexican citizens who are in the US legally? Mexican citizens who are in the US illegally?
Without that clarification, your thesis is terribly hard to understand.
Plus ... have you written at least the outline for your entire paper? If you haven't, then you need to concentrate on that before you worry much more about your thesis.
See the writing process:
Follow the writing process, whether you're writing for science, history, English, or whatever:
Prewriting: Brainstorm, research, plan, outline, thesis statement
Writing: Write first draft by starting with section II of your outline; write the introduction after the body of the paper is written; write the conclusion last.
Polishing: Revise, concentrating first on the body of the paper, then the intro, then the concl (revision = making sure ideas are logical and sequential and support your thesis); proofread (spelling, grammar, usage, etc.)
