I guess the focus is on this young man who had to find a way to join his family, with no resources, at a time where Jews were not widely accepted? alone?? It sounds like a great story but I guess we focus on the obstacles
a) no resources and alone
b) Impact of being a Russian Jew - does that present a problem travelling around Europe? how are the Russians or Jews viewed at that time?
c) way to travel - how is he getting around? does he have any skills or education? Speak another language?
d) what would happen when he arrives in the US
Always love a good immigrant story....I think we need to know more about the protagonist - I don't think it's as important as to why he is separate from his family, but more about his quest to find them in the US.
