Input: Question: How ling had the United States been a country when Danish emigrated there? Passage:He adopted "Danish" as his Takhallus (pen-name). Bachay, Titli, Phool, his first collection of poems, was published in 1997. He quickly garnered recognition for the anger he expressed through his works, in which he often made reference to his experiences as a member of the African diaspora; his work attracted the attention of leading Urdu critic Shamsur Rahman Farooqi, who had them published in Indian literary journal Shabkhoon. In 2000, he emigrated to the United States; he had remarked to a friend that he would prefer to be "a third class citizen of a first class country than a first class citizen of a third class country," but put off going through the procedures for almost two years due to his ambivalence about leaving his home. He first took up residence in the Kew Gardens neighborhood of Queens, New York City; he chose it because of its diversity, which helped him to feel less of a stranger as well as affording him the opportunity to study others' cultures. At first, he could only find job as a security guard, but he eventually joined the faculty of New York University; he later moved to the University of Maryland as a language consultant.
