On July 17, 2017, Portuguese citizen Joao Pereira da Fonseca pled guilty to conspiring to unlawfully export U.S.-origin goods and technology to Iran and to defraud the United States. He was sentenced to 20 months in prison, after which he will face deportation proceedings. Between October 2014 and April 2016, Fonseca, a mechanical engineer, used a Portuguese company as a front company to purchase technology with commercial and military applications from two U.S. companies on behalf of an Iranian client. One U.S. company manufactures machinery for the production of optical lenses; the other produces machines that test inertial guidance system components. Fonseca misled the U.S. companies as to the end-user and ultimate destination of the technology, which the companies believed to be Fonseca’s employer in Portugal. Fonseca traveled to the United States twice between 2015 and 2016 for training on how to install and maintain the technology. He was detained when leaving the United States in April 2016 and has been in U.S custody since then. None of the technology was exported to Iran.
