Human Rights in Cuba: The Need to Sustain the Pressure, published by Americas Watch in 1989 mentions a US-Cuba immigration agreement (1984) renewed in 1987. Under this agreement, the United States accepts immigration or refugee applications from any Cubans and, in return, Cuba agrees to take back the US Mariel Boatlift refugees who could not adjust to the American society (for instance, those who committed crimes in the United States [Americas Watch; Telephone communication with an officer of the US Immigration Press Information Center, Washington]. The vast majority of the Mariel Boatlift refugees have adjusted to American society and were allowed to remain as immigrants [Telephone communication with an officer of the US Immigration Press Information Center, Washington]. Five Mariel detainees were deported to Cuba in December 1988 and nine more deportations were pending in 1989 [Americas Watch].

No information regarding the voluntary return of a Mariel refugee currently is available to the IRBDC.
