Taiwanese Ministry of Foreign Affairs Bureau of Consular Affairs

The Taiwanese Ministry of Foreign Affairs Bureau of Consular Affairs (BOCA) handles the consular functions of the Republic of China’s government. It is responsible for issuing passports and other travel documents to Taiwanese citizens. The bureau also processes visa applications for foreign nationals wishing to visit Taiwan. In addition, BOCA provides assistance to Taiwanese nationals who encounter difficulties while abroad, such as emergencies, legal issues, or lost documents. Its services are delivered through a network of overseas representative offices and domestic service centers.

In November 2016, BOCA disclosed a cybersecurity incident that affected its email system used for communication with overseas offices. Attackers gained unauthorized access to email accounts, potentially compromising approximately 15,000 files containing travelers’ personal information. The exposed data included names, identification numbers, passport details, phone numbers, and addresses. The breach was detected after irregularities were noticed in the affected accounts, prompting an internal investigation and public acknowledgment. At the time of disclosure, no victims had reported related problems stemming from the compromised data.

BOCA’s core competency lies in its specialization of consular affairs, which distinguishes it from other bureaus within the Ministry of Foreign Affairs. It regulates the issuance and renewal of passports, ensuring compliance with national and international standards. The bureau also oversees the provision of consular protection and assistance, acting as a liaison between Taiwan’s diplomatic missions and citizens abroad. As a subordinate unit of the Ministry of Foreign Affairs, BOCA operates under the executive branch of the Taiwanese government and reports directly to the ministry’s leadership. Its position within the government structure links it to both domestic policy formulation and international diplomatic engagement.
