The United States embassy has warned local residents about an email scam in which Cambodian citizens have been receiving messages making false offers of green cards or diversity visas that would allow them to move to the US. In a statement issued yesterday, the embassy said such emails often request payment for services that are typically free and attempt to masquerade as official government communications. “Any person who receives an e-mail that mentions Diversity Visa or promises you a Green Card should consider the contents illegitimate and fraudulent,” the statement read, advising recipients of the messages to forward them to the embassy’s Immigrant Visa Unit at [email protected].
