Understanding Green Card Marriage Fraud explores personal accounts of participation in Green Card marriage fraud (GCMF), also known as 'cash-for-vows', by legal and illegal immigrants, U.S. citizens, and marriage fraud brokers. This book reveals the various roles played by the marriage fraud brokers and others who aid, abet, or otherwise act as accessories to GCMF. Additional details provide the reasons why people commit GCMF and the methods they use in order to deceive immigration officials. Today, Green Card marriage fraud has acquired new importance due to world upheavals and the plight of refugees. The division in American public opinion has become political football and has led to various changes in immigration policy, often depending on the occupant of the White House. The study of Green Card marriage fraud can serve as a microcosm of the federal government's involvement in crime control. The author puts Green Card marriage fraud in the context of current immigration policies, suggesting necessary policy reforms since current rules and procedures are ineffective in detecting such fraudulent marriages. In unraveling the mystique surrounding GCMF, the methods of crime control and migration control converge revealing the 'crimmigration phenomenon' with GCMF falling in the middle of this nexus.
