The were cons about Ellis Island. One con was that there were over 250,000 immigrants were sent back because they failed to pass the tests. Another con was that some people that were sick had to stay in a hospital until they are eligible to go in to America. A third con was that people who they weren't quite sure about letting them in America had to stay in detention as in held there.
Daily life for the people that were stuck on Ellis Island were bad. Even thought they don't have freedom they are still fed which could be better than some of their old countries. It was still pretty bad though. They had to sleep in pens that were to small for all of them. They were also very cold a night.
