Application Requiring Further Action

On this page:


A refusal under Section 221(g) of the U.S. Immigration and Nationality Act (INA) means that essential information is missing from an application or that an application requires further administrative processing. The consular officer who interviews you will tell you at the end of your interview if your case has been denied under Section 221(g). The officer will either tell you that the case has to undergo administrative processing, or will ask you to submit additional information.  Your visa application will be reconsidered upon receipt of your response or when administrative processing is complete.  Please be advised that for U.S. visa purposes, including ESTA (, a 221(g) decision constitutes a denial of a visa.

Submitting Additional Information

If further information is required, the officer will tell you how to submit that information. As part of this process, you will be given a written letter and will have 12 months from the date of your application to submit the requested documents without having to pay a new visa application fee. After one year, an application refused under Section 221(g) will be terminated.

If the American Institute in Taiwan requested additional information or documentation from you, you may be required to submit those documents via email or to submit original documents at a document delivery office. This web page explains how to submit your documents to the American Institute in Taiwan.

Administrative Processing

Some visa applications may require further administrative processing, which takes additional time after your interview with a consular officer. You will be advised of this possibility during your interview. Most administrative processing is resolved within 60 days of your visa interview. When additional administrative processing is required, the length of processing time will vary based on the circumstances of each case. You are reminded to apply early for your visa, well in advance of your anticipated date of travel. 

Applicants can help make this process go faster by being prepared for their visa interviews. They should bring a copy of their resume or curriculum vitae (CV); a list of their publications (if any); a summary of their past and future research; information on their advisor or sponsor in the United States, including an invitation letter detailing the applicant's planned activities or specific study in the US; sponsor's mailing address and telephone number (for example, a copy of his/her webpage); and a list of references.  Applicants who will be attending conferences in the US should also bring information about the conference, including abstracts of any presentation, if applicable.  This information should be in English.  Applicants should also be ready to answer specific questions about their research plans in the United States.

Please note that while it is recommended you bring these documents to the interview, if your case requires administrative processing, you will also be asked to submit the required documents electronically via email.  Instructions will be given at the time of interview.

Applicants who do not bring complete information to the interview (e.g., a resume and research summary) may have their applications delayed even further, or may be refused a visa and asked to apply again.  The more information and documentation an applicant provides during the visa interview, the better the application can be evaluated.  If you are unsure about whether or not to bring a particular document, please bring it with you in case the interviewing officer wishes to review it.

If you have submitted your application to AIT and have been provided an administrative processing case number, you can check the status of your case any time on the Visa Administrative Processing Case Status page. You will need to enter the administrative processing case number and the verification code on the screen.  Please check the online status regularly as this will be the only means by which you will be notified about the status of your case.  Once administrative processing is complete, you must return your passport to AIT within 120 days

Note: Before inquiring about your visa status, you or your representative must wait at least 60 days from the date of your interview or the submission of supplemental documents, whichever is later. Please be patient.
