Final answer:
The Palestinian-American Aid Society assists Palestinian immigrants in the U.S. with language, integration, and professional development. It provides a supportive community to aid in the adjustment to a new country, helping to reduce prejudice and promote assimilation.
Step-by-step explanation:
The local and regional association that helps Palestinian immigrants adjust to life in the United States is called the Palestinian-American Aid Society. This organization aims to reduce prejudice towards Palestinian refugees and facilitate their assimilation into American society by helping them learn English, adapt to American ways of life, and develop marketable work skills. The importance of such an organization is underscored by historical challenges faced by immigrants, including the need to find solidarity and assistance within social groups sharing their cultural heritage.
While the Palestinian National Authority has its own diplomatic service, and the Palestine Liberation Organization (PLO) has been a significant representative body for Palestinians, these entities do not provide the localized community support that a group like the Palestinian-American Aid Society offers to individuals and families who have relocated to the U.S.
