Kolkatta US embassy : Applications from South India not to be entertained

From a Press Release :

Calcutta Will No Longer Routinely Accept Visa Applicants from South India
Due to staffing shortages anticipated over the next several months, the U.S. Consulate General in Calcutta is suspending its practice of routinely accepting applications from visa applicants resident in south India. People who already have an appointment scheduled with our Consulate General in Calcutta will still be seen, but new appointments should not be scheduled for an interview in Calcutta unless the applicant resides in Assam, Manipur, Meghalaya, Nagaland, Tripura, Bihar, Orissa, West Bengal, Arunachal Pradesh, Sikkim, Mizoram, Jharkhand or the Andaman and Nicobar Islands. The consular section at the US Embassy in New Delhi will continue to accept regular appointment requests from south India residents made via the Internet-based appointment system at http://ttsvisas.com/

Strong demand for visas to visit the United States has led to substantial waits for interview appointments at all US consular sections in India. Applicants are advised to schedule their interview appointment as soon as they learn they have a need to visit the United States. Each consular section in India has arrangements to accommodate applicants with an emergency need to travel. Emergency appointments are reserved for those residents of a particular consular district who must travel for urgent medical care not available in India, family emergencies (such as death or critical illness), unanticipated business reasons, or other emergency situations. In addition, consular section will ensure that all student visa and exchange visitor visa applicants who have not been refused a visa twice within the last six months will be able to schedule an appointment before the date they are required to report to their school or program.
Check the website for the Consulate General nearest your place of residence for more information about that office’s emergency appointment procedures if you think you might qualify to be seen early.
