Final answer:
Intelligent immigrants generally had an easier time assimilating into American culture due to their education level and skillsets that aided in language acquisition and economic adaptation. However, during the 1920s to 1965 immigration was limited, and post-1965 saw an increase in Muslim immigrants, many with higher education due to political unrest in their home countries.
Step-by-step explanation:
Those immigrants who were intelligent had an easier time assimilating into American culture. This is because intelligent immigrants were often more educated and possessed the skills needed to adapt more quickly to their new environment. They could learn English faster, understand American customs, and bring skills that were in demand. However, it is important to recognize that various factors influence an immigrant's ability to assimilate, including education, language proficiency, and social support networks.
During the period from the 1920s until 1965, immigration policies curtailed immigration significantly, but the pattern of immigration changed after 1965, introducing a higher number of Muslim immigrants, many of whom were highly educated and seeking better opportunities amidst political unrest.
Assimilation can lead to immigrants losing some of their cultural identities as they take on the majority culture's ways. This is often a complex process influenced by socio-economic factors, including the ability to speak English and acquire marketable work skills.
