What is Mukherjee's thesis in two ways to belong to America?

In "Two Ways to Belong in America," Bharati Mukherjee explores the complexities of identity and belonging for immigrants in the United States. She contrasts her own experience as a naturalized citizen, who embraces the American culture while maintaining her Indian roots, with that of her sister, who chooses to remain an Indian citizen and resist assimilation. Mukherjee argues that the concept of belonging is multifaceted and can manifest differently based on individual choices and experiences. Ultimately, she highlights the tensions between cultural identity and the desire for acceptance within a new homeland.
