布里亚科夫被控借着在纽约市一家俄罗斯银行任职的身份，为俄罗斯外事情报局搜集信息。
检方文件显示，布里亚科夫可能会在星期五提交认罪或无罪申辩。他定于4月4日在曼哈顿联邦法院受审。
美国司法部2015年1月宣布布里亚科夫被逮捕，此前他与一名联邦调查局便衣特工多次秘密会面，他以为这名特工是一家能源公司的分析师。

U.S. court documents indicate a Russian citizen accused of spying will register a plea Friday, ahead of his federal trial next month.
Evgeny Buryakov is accused of posing as an employee of a Russian bank in New York City to gain information for Moscow’s foreign intelligence agency, known as the SVR.
Prosecutors’ documents indicate Buryakov could register a plea of guilty or not guilty on Friday. He is set to face trial in federal court in Manhattan on April 4.
The U.S. Department of Justice announced Buryakov’s arrest in January 2015, after he held multiple secret meetings with an undercover FBI agent that Buryakov believed to be an energy company analyst.
Prosecutors say he conspired with two other Russian men to gather U.S. economic intelligence, including details about U.S. sanctions against Moscow. He is also accused of trying to recruit New York residents as intelligence contacts.
