Marshall Taheri, an A-V rated attorney who has been practicing law for more than 45 years to include U.S., and international criminal defense, is a former advocacy judge, and law professor emeritus.

The Marshall Taheri Law Group is dedicated to providing top quality representation in all phases of white-collar criminal defense from investigations to trial. When possible, we actively negotiate on our clients’ behalf with the United States Attorney’s Office and administrative bodies to achieve favorable results before trial. When cases proceed to trial, we are dedicated to aggressively representing our clients’ interests and needs.

We represent people nationally and internationally who are facing FBI, CIA, and grand jury investigations and/or who have been accused of RICO, money laundering, and asset forfeiture, as well as violation of SEC, IRS, HUD, FDA, DHS regulations, and the Federal False Claims Act – Qui Tam cases.

Further, we represent those who have been accused of violation of labor laws, currency transmission, export control laws, and the Foreign Corrupt Practices Act. We also represent people who have been accused of bank fraud, counterfeiting and forgery, credit card fraud, embezzlement, fraudulent bankruptcy, insider trading, insurance fraud, mail and wire fraud, Medicare fraud, and tax fraud.

The firm possesses the extensive knowledge of international white collar criminal defense to assist our clients at the time of need in the following international criminal cases: foreign corruption and bribery, money laundering, human trafficking, international drug trafficking, weapons transaction, kidnapping, violations of export controls, violations of currency transmission, industrial espionage, piracy and intellectual property theft, and computer crimes.

We understand the language of the law around the world. We are fully conversant with current U.S.- international bilateral treaties and conventions. We travel to other countries to represent our clients in foreign courts. Further, we utilize the assistance of the U.S. State Department in Washington, D.C., U.S. Justice Department, U.S. Attorney’s Office, U. S. embassies and consulates abroad, as well as the authorities of foreign countries in pursuit of achieving our clients’ freedom.

To be considered an international crime, the crime must be committed in a foreign country or jurisdiction, i.e., money laundering, human trafficking, piracy and intellectual property theft, and with a few exceptions, may become an international crime if it is committed on foreign soil.

U.S. citizens charged with money laundering, human trafficking or other international crimes may be tried before an international tribunal or in the court of a foreign country. However, foreign nationals indicted for crimes that involve the illegal transfer of assets, drugs or other goods across U.S. borders may be prosecuted in a United States federal court. How and where an individual is prosecuted and the procedures used in that court will likely be defined by international treaties and conventions.

During the past decade and as a result of business globalization, the number of people traveling, living, and working abroad has increased significantly. During the same period, drug use increased, and arrest for such cases increased substantially. Being arrested and charged with a criminal offense in a foreign country, held in a jail and appearing in court where you do not understand the language, culture, or the local customs is a terrifying situation.

Practice Areas

Our Attorneys


In conjunction with our international criminal justice practice, we also represent our clients in matters involving extradition proceedings. Many times, at the request of the U.S. government, a U.S. citizen who is arrested in a foreign country for the purpose of being extradited to the United States intends to challenge the extradition for substantive legal reasons.

We also represent foreign nationals who are arrested in the United States for the purpose of being extradited to his/her country or a third country, pursuant to a request by the foreign government, and intends to challenge the extradition for substantive legal reasons.

Transfer of Prisoners

We represent prisoners in connection with their request to be transferred to their home countries under the provisions of the prisoner transfer treaties between the United States and certain foreign countries.

Pursuant to the prisoner transfer treaties between the United States and certain foreign countries, U.S. citizens serving sentences in foreign countries may be eligible to be transferred to the United States to serve the remainder of their sentences close to home.

Foreign inmates serving federal sentences as well as state sentences in certain states may apply to be considered for transfer to their home countries to serve their sentences, however, there are some restrictions on eligibility.
