Texas billionaire Allen Stanford is expected to appear in court Friday morning to face criminal charges, but the venue for the hearing is unclear, Stanford's lawyer said Thursday.

I don't know where he is going to appear in the morning and the FBI doesn't know where he is going to appear in the morning, attorney Dick DeGuerin told Reuters.

Stanford surrendered to U.S. authorities in Virginia on Thursday after criminal charges were filed against him.
