Final answer:
Post-World War II, the Japanese American Issei faced financial hardships, while the Nisei struggled with assimilation due to enduring prejudice, with assistance from religious and civic groups.
Step-by-step explanation:
After World War II, the settlement pattern for the Japanese immigrants in America, specifically the Issei and Nisei, underwent significant transformations. The Issei, who were the first generation of Japanese immigrants, faced impoverishment due to the loss of their businesses, occupations, and properties during their internment. Consequently, many became dependent on their children, the Nisei. The Nisei, on the other hand, despite being American citizens, grappled with the challenge of assimilation due to persistent prejudice. Although financial security was the most pressing issue for the older generation of internees, assimilation into society posed a greater challenge for the younger generation, who received aid from various religious and civic organizations.
