It was the lead single for the duo's debut album, Graham Nash David Crosby.

Nash wrote "Immigration Man" about an unfortunate moment he had with a U.S. Customs official when he tried to enter the country.

The customs official held him up interminably, and soon people started coming up to Nash for his autograph.

Nash also explained why he chose a picture of the earth from space for the cover of the sheet music for "Immigration Man."

"[1] The music of "Immigration Man" is mid-tempo West Coast rock in the Crosby, Stills and Nash or Buffalo Springfield tradition.
