Qualifications for an Expedited Interview Appointment
Consular sections overseas may be able to expedite your interview date if there is an urgent, unforeseen situation such as a funeral, medical emergency, or school start date. The process to request an expedited nonimmigrant visa interview varies by location. You should refer to the instructions on the website of the
Embassy or Consulate Visa Section where you will interview, or on their online appointment scheduling site. You will need to provide proof of the need for an earlier appointment.
In all cases: You must first submit the online visa application form (DS-160), pay the application fee, and schedule the first available interview appointment. Only at this point will a consular section consider your request for an expedited appointment.
Note: Travel for the purpose of attending weddings and graduation ceremonies, assisting pregnant relatives, participating in an annual business/academic/professional conference, or enjoying last-minute tourism does not qualify for expedited appointments. For such travel, please schedule a regular visa appointment well in advance.
