The Tsarnaev family settled in Cambridge after applying for, and receiving asylum, a decade ago, according to testimony from homeland security officials at Congressional hearings in the aftermath of the blast. Congressman William Keating (D-Mass.) was among the federal lawmakers who met with Russian officials in May and told reporters upon his return that a domestic violence arrest prevented Tamerlan Tsarnaev from receiving citizenship, but Dzhokhar became a naturalized U.S. citizen at a ceremony held in Boston on September 11, 2012.
Dzhokhar's parents are back in Russia living in the Dagestani city of Makhachkala. It is unclear if they have traveled to the United States to attend their son's court hearing tomorrow. His mother, Zubeidat Tsarnaev, has an open arrest warrant in Massachusetts in connection with a shoplifting charge and could be arrested upon her return, prosecutors have said.
Tsarnaev has been held at Fort Devens, where supporters have deposited money into his prison account, he told his mother in a phone call to Russia.
