Following the Vietnam War, many people from Southeast Asia were paroled into the United States with an indefinite immigration status. In 2003, a new rule was developed to allow for adjustment of immigration status for some of these people. According to the new rule, all nationals of Vietnam (and some others, for example, nationals of Cambodia) who were paroled into the United States through the Orderly Departure Program were eligible to apply for permanent resident status.
Explanation
Answer: B - This paragraph is mainly about the group of Vietnamese Nationals who were paroled into the United States under the Orderly Departure Program with indefinite immigration status. In 2003, a new rule made everyone in this group of Vietnamese Nationals (and others) eligible to apply for permanent resident status. Accordingly, anyone who is not eligible to apply for permanent resident status must not be part of this group of Vietnamese Nationals, which is equivalent to Response B.
Responses A and C fail to recognize that others, such as nationals of Cambodia, were also eligible to apply for permanent resident status. Responses D and E contradict the information that everyone in the group of Vietnamese Nationals who were paroled into the United States under the Orderly Departure Program was eligible to apply for permanent resident status.
