Records of folks leaving the US?? (American, grandmother, father, history)

[Uconn97]

Hi Everyone - I am just starting the process of looking back at my family history. I know it will be a short one in the US so I don't expect to get much further since I know my great grandparents left the US to go back to the old country after being here a short time. What I would like to know if when they went back? Here is what I know:

My great grandfather and great grandmother came here in 1914 from Lisbon, Portugal. They arrived in providence, RI on May 4th, 1914. I know they went back to portugal before my grandfather was born 1922/1923 so they were not here too long. Does anyone know if there are any records that show non-US citizens leaving the US??

Thank you!

The only thing I can think of would be shipping line passenger lists. Not sure though whether you'd look at point of embarkation or debarkation.

There are definitely others in your situation. Many immigrant groups had or have local clubs that might have information. Like Portugese-American Association, for instance. I just made that up, but they had names like that. Some still have active groups.
