(Reuters) -Former Binance chief Changpeng Zhao must stay in the United States for the time being, a federal judge said on Monday, after the founder of the world's largest cryptocurrency exchange pleaded guilty to violating U.S. anti-money laundering laws.

Zhao will be required to stay in the United States until the Seattle court considers whether he should remain through his sentencing hearing in February, or if he should be allowed to return to the United Arab Emirates, where he is a citizen.

Zhao, who is also a citizen of Canada, stepped down as CEO of Binance last week after pleading guilty to willfully causing the exchange to fail to maintain an effective anti-money laundering program.

U.S. District Judge Richard Jones in Seattle said he would review whether Zhao should have to stay in the United States after the U.S. government appealed a decision by another judge to allow Zhao to return to the UAE before his Feb. 23 sentencing hearing. Zhao agreed to a $175 million bond as part of the bail agreement.

Binance Holdings agreed to pay over $4.3 billion and pleaded guilty to breaking U.S. anti-money laundering and sanctions laws.

Zhao faces a maximum prison sentence of 18 months under federal guidelines and has agreed not to appeal any sentence up to that length. Prosecutors will take a position on how much jail time to seek closer to Zhao's sentencing, a Justice Department spokesperson said last week.

The government had said it may be unable to secure Zhao's return to the United States given it has no extradition treaty with the UAE.

But lawyers for Zhao disputed that he was a flight risk, noting that he paid a "substantial" bail package and voluntarily came to the United States to accept responsibility for his actions.
