As its name implies, reunification is when people are reunited with a family member who already lives in another country. Ever since the laws were amended in 1968, reunification has become the most common reason for immigrating to America. A US citizen or permanent resident can sponsor their parent, spouse, or child. The original family member can be living in the United States for any number of reasons, including work or even as a refugee. Recently, however, the president has been attempting to reform the policy by cutting family-based immigration, ultimately restricting the movement of foreign families.
