As of January 1, 2012, the U.S. Consulate General in Chennai is no longer processing Immigrant Visa petitions. The U.S. Embassy in New Delhi and U.S. Consulate in Mumbai will be the only consular posts in India accepting Immigrant Visa applications. Individuals who are currently in the process of applying for an Immigrant Visa at the U.S. Consulate in Chennai are advised to contact ChennaiIVU@state.gov for further details and instructions.
Please also note that visa processing in India has becoming increasingly subject to administrative delays. When applying for a visa, an applicant may encounter unforeseen and undetermined delays due to additional administrative processing. The admininstrative delays may be on account of name checks, security clearances, or review of petition information. Applicants are therefore advised to be prepared and plan accordingly for these possible adminstrative delays.
