Where the A train dead-ends at Lefferts Boulevard, Liberty Avenue stretches on into the heart of the enclave known as Little Guyana, part of the larger Richmond Hill neighborhood. To most Americans, and even New Yorkers, this population remains obscure. “People don’t know who we are,” says Lakshmee Singh, a talk show host and community leader in Queens, Richmond Hill, once a predominantly German and Italian neighborhood, has seen a steady stream of Guyanese immigrants since the 1970s. Today, it’s home to the largest Guyanese community outside of Guyana itself, with Guyanese immigrants representing the second largest foreign-born community in Queens.
