Travelers from some countries may have to post a bond of up to $15,000 before entering the U.S. as part of a new year-long pilot program, according to a Federal Registrar notice.

Covered visa applicants will be required to post a bond of up to $15,000, but the State Department gave consular officers three options for bond amounts: $5,000, $10,000, and $15,000. Consular officers can determine the exact amount of the bond “based upon the applicant’s circumstances.”
