It is my understanding that Ellis Island was the immigration processing site for all 3rd class passengers arriving in USA. First and second class would be quickly cleared on their ship at the port of arrival and only those with legal problems or who were sick would join the 3rd class on the ferry to Ellis Island where the process was more rigourous.
