This idea is about avoiding illegal immigration in America. This idea takes advantage of the Social Security Number given to all American Citizens. So, if someone crosses the border illegally, he/she will not possess SSN. If we isolate people without SSN, we can completely catch hold of every single illegal immigrant in America. We can make it still better, efficient, less costly by making it compulsory for companies, big, small or petty shops, to check the SSN status, before giving them job. Next we can make compulsory for every rental house owners, to check SSN status. No job, No shelter, No more illegal immigrants. Through this way, we can cut costs of police force, who may waste resources otherwise, by checking all immigrants.
