Hayes is currently in Singapore, Greenwood told District Judge John Koeltl, of the Southern District of New York, according to the transcript.

“We have discussed with counsel how to arrange for a voluntary surrender, and he has proposed appearing within the United States in Hawaii and having his initial appearance there and then,” she said in the transcript. 

Greenwood said Hayes could continue to reside abroad, traveling to Hawaii for virtual appearances during the initial stages of the legal process. He would travel to New York if and when the case proceeds to the trial phase.
