PD, you can immigrate to Mexico and after due process, you can become a Mexican citizen with all the rights accorded to citizens. Many Europeans have come to Mexico that same way. The same applies to America.
Immigrants in America are guests and can be deported for almost any type of violation of the law. We choose not to in many cases, but our immigrations laws are not lenient. It's the enforcement of the law that is lacking. As you may have read, many muslim legal immigrants have been deported for technicalities because they simply were persona non-grata.
I support legal immigration. And I support legalizing the people who are already here.
