What immigration station did immigrants use when crossing the atlantic ocean?

immigrants who came to the United States in the eastern coast, across the Atlantic Ocean, used Ellis Island as their main immigration station.

so, based on the research i've done. the u.s. government were always on a wild goose chase just to take down castro. he then retired his trone to his brother raul in 2008 due to some health issues. so it's obvious your answer would be:

castro had no allies from which he could receive aid.

hope this and have a fantastic day!
