On Sept. 24, the Department of Justice filed a civil denaturalization complaint against Gurdev Singh Sohal, also known as Dev Singh, also known as Boota Singh Sundu, who obtained his U.S. citizenship in 2005 despite having been ordered deported in 1994. Instead of leaving the country based on his 1994 deportation and exclusion order under the name Dev Singh, Sohal used a different identity, with a new name, date of birth, and date of entry into the United States, to naturalize. He did not disclose his prior immigration history under the Dev Singh identity in any of his immigration applications or proceedings when he naturalized under the Gurdev Sohal identity. Expert analysis in February 2020 confirmed that the fingerprints submitted under both identities came from the same individual. The analysis was only made possible after DHS digitized the paper fingerprint submission documents from older immigration files.
