Xin Gu of Dalian, China, faces up to 30 years in prison when he's sentenced Oct. 19.
Prosecutors in Houston say Gu was on trial when he pleaded guilty Tuesday to conspiracy to commit bank fraud and aggravated identity theft.
Gu was arrested Feb. 3 after posing as someone else at a Chase bank in Houston. Investigators say he presented a fake passport and bogus documents in the victim's name.
Prosecutors say a week earlier a fictional authorized user was added to the victim's accounts. Investigators believe a woman helped Gu withdraw the funds.
Gu remains in custody as the investigation continues.
