summarize the key points of the paper:Glick-Schiller, Nina, Linda Basch, and Cristina Szanton Blanc. 1995. "From Immigrant to Transmigrant: Theorizing Transnational Migration." Anthropological Quarterly 68(1):48-63.

In their 1995 paper "From Immigrant to Transmigrant: Theorizing Transnational Migration," Glick-Schiller, Basch, and Szanton Blanc introduce the concept of "transnationalism" to describe a new form of migration characterized by the sustained ties and connections that migrants maintain with their countries of origin while settling in a new host country. Here are the key points of the paper:

**Definition of Transnationalism**: The authors define transnationalism as a process that transcends national boundaries, where migrants engage in multiple national affiliations and practices, effectively combining elements from both their home and host countries.

**Migration Dynamics**: The paper highlights a shift in understanding migration. Traditionally viewed as a one-way journey, migration is reframed as a circular process where individuals move back and forth, maintaining strong ties to their origin communities.

**Social and Economic Networks**: The authors emphasize that transnational migrants are often embedded in extensive social networks that facilitate economic, cultural, and emotional exchanges across borders. These networks can include family, friends, and community organizations.

**Implications for Identity**: The paper discusses how transnationalism influences migrant identities, leading to multifaceted identities that are shaped by experiences in both home and host countries.

**Policy Considerations**: The authors argue that understanding transnationalism is crucial for policymakers, as traditional immigration policies may not adequately address the realities of transnational lives and the needs of migrants who operate across borders.

**Research Directions**: Glick-Schiller and her co-authors call for more research into transnational practices and their implications for migration theory, advocating for a multidisciplinary approach that combines anthropology, sociology, and other fields.

Overall, the paper lays the groundwork for a new framework for understanding migration that captures the complexities of how people navigate multiple social and national landscapes.
