Khandaker Nazmunnessa Ullah, a Bangladeshi native who came to the U.S. in 1994, is a married mother of four and owns a convenience store with her family in Nashua. Federal prosecutors are seeking to strip her of U.S. citizenship, alleging she lied about her immigration history when applying for naturalization in 2007. Authorities claim fingerprint records show Ullah was ordered deported in 1995 under a different name before being granted lawful permanent residency in 1996. No court records suggest she committed any crime or human rights abuses.
