Taiwanese in the U.S. can call 518-956-5673 for three-level authentication services.
Many Taiwanese need to handle affairs in mainland China, such as when one spouse is from the mainland and the other is from Taiwan, including buying or selling property, registering children's household registration or nationality, and applying for immigration procedures for a spouse.
However, the Chinese government does not recognize the Republic of China or dual nationality. Therefore, Chinese embassies and consulates do not accept Taiwanese passports as proof of identity. If authentication materials involve "Taiwan," Chinese embassies and consulates also have specific requirements, such as ensuring that references to "China" and "Taiwan" in documents comply with regulations.
Thus, if Taiwanese individuals wish to have their documents authenticated by Chinese embassies or consulates (three-level authentication), they must pay attention to wording and ensure that identity documents meet embassy requirements.
