The fate of an Ivy League-educated man who was convicted of violating the Iran trade embargo after his family sent him millions of dollars from Iran rests with a federal judge in Manhattan.

Judge John Keenan is expected to sentence Mahmoud Reza Banki on Monday. Banki faces up to 25 years in prison after he was convicted in June of violating the embargo and operating an unlicensed money transmitting business.

The Tehran-born Banki is a U.S. citizen. Banki’s lawyers had said the 34-year-old Princeton University graduate had $3.4 million deposited into his bank accounts by family members and was unaware that an informal banking system let an equal amount of money move into Iran.
