Passport Application sample

This passport sample from 1922 indicates that the applicant was born in Switzerland and provides the name of his father and the date of immigration. Also included is the reason for the trip and a picture. Earlier applications do not give pictures and as much information, but is it possible that your ancestor made a return trip "home" to visit family? I'm going to be spending some time this evening taking a look at the recently released US Passport Applications and images 1795-1925.
