In fact, the International Civil Aviation Organization specifies place of birth as a key element of biographic data for machine readable and e-passports.
The U.S. government notified the St. Kitts and Nevis government that versions of the St. Kitts and Nevis passport that lack key elements of biographic data have caused the U.S. government to require additional documentation from applicants for U.S. visas to evaluate their eligibility.
