Yes what you say can be true. But someone who follows the laborious legal process and meets the requirements legally deserves citizenship more than someone who just ignores the law and enters illegally - their first act as a prospective citizen to commit a crime. How can someone, whose first act in the country is to break it's laws, be trusted fully?
I know people who have migrated to this country legally and have gone through ten years of jumping through hoops, following the torturous process, some have been through horrible situations in their home country, but they endure and follow the law. I know an African brother who's entire family was murdered in the Congo, but he's going through the legal process. What are we saying to these law abiding souls if people who ignore the whole process receive the same treatment? How can a society survive with two tier laws?
God Bless
