In "The Godfather", what favor did Vito grant Nazorine the Baker during the wedding?

In “The Godfather,” Vito Corleone granted Nazorine the Baker’s request by helping Enzo avoid deportation. Enzo was an Italian prisoner of war who had fallen in love with Nazorine’s daughter, Katherine, and faced being sent back to Italy after the war.

Nazorine approaches Vito during Connie Corleone’s wedding, where the Don hears private requests from friends and acquaintances. Rather than asking for money or revenge, Nazorine wants Enzo to remain in the United States so the young couple can stay together. Vito uses his political influence to arrange Enzo’s legal protection and employment.

The favor also reinforces an important theme in the film: Vito’s power operates through personal relationships and unofficial obligations. The baker’s wedding cake is part of the celebration, while the private conversation reveals how the Don’s influence extends into immigration and government affairs. This scene is sometimes confused with the later hospital sequence, when Enzo helps Michael appear to have protection outside the hospital.
