Illegal Immigration

In my opinion illegal immigration is wrong. People say America is a free country, and they should be able to come into the country, but wouldn't i get arrested for trespassing on some ones private property. That is pretty much the exacted same thing. Being some where without permission. It is breaking the law to come into the country without being legal. So why should it be aloud. In the long run the United States will be over populated and over run. Some would say it is morally wrong to build a fence but it is just as wrong to break the law when first entering the country. Immigrants want all these rights and want things to be fair between legal citizens and immigrants but how can we make rights for people who are breaking the law every second they are in the country. The rights that are wanted should be earned by becoming citizens. Also the English language should be learned before being able to work.
