Northern Mariana Islands Immigration: Hearing Before the Subcommittee on Mineral Resources Development and Production of the Committee on Energy and Natural Resources, United States Senate, One Hundred Third Congress, Second Session on the Issues Associated with Immigration Into the Commonwealth of Northern Mariana Islands, September 22, 1994 [open pdf - 2MB]
From the opening statement of the Hon. Daniel K. Akaka: "Today's hearing will focus on issues associated with immigration to the Commonwealth of the Northern Mariana Islands, including the increase in the number of non-residents, the lack of an efficient monitoring system to track their entry, as well as reports of labor, physical and sexual abuses against alien workers. Many of these abuses have been directed against women from the Philippines and the People's Republic of China. I am very anxious to hear from local and Federal officials on what actions they have undertaken or plan to undertake to address these problems. There is growing concern in Congress that the only way to stem these serious abuses is to crack down on an immigration policy that offers an open door to alien workers and organized crime. One solution would be to strengthen Federal oversight, assistance, and enforcement in the Commonwealth."
