Immigration Reform

Immigration Reform is the new hot issue, now that Gay Marriage has been laid to rest for the most part. To Conservatives, it's a tighter border and stricter rules, with only certain types of laborers allowed, even if there is a demand for manual labor. To Progressives and Libertarians, as long as there is a demand for labor which immigrants are willing to fulfill, immigration should be a simple process. What are your thoughts? What have been your experiences? I'd love to hear from you.
