US-Taiwan diplomatic relations are unique, and there is no US Embassy in Taipei. The AIT oversees US interests in Taiwan, handles liaison with the Taipei government, and issues US visas.
For those who may have had immigrant and nonimmigrant visa interviews at AIT after 18 March 2011, AIT is instructing that you visit the AIT’s visa processing website to reschedule.
Emergency matters should contact the AIT website directly and follow instructions there.
There has been no indication as to when the visa section will re-open for general business. If you have questions about this or any other issues relating to immigration and nationality law, please contact us. –jcf
