Nothing can be said about the processing times at the Chennai Consulate for H-visa processing.
I applied for H1B revalidation through the drop-box scheme at chennai - I applied on 19th May and got my passport with visa stamping on June 2nd.
We had submitted extensive / exhaustive documentation - Original I-797, LCA, employer letter, pay stubs for last few months, original certs, photographs of offices, business cards of few colleagues, copies of recent tax returns etc.
While I got my H1B stamping...however, my wife's H1B stamping is still being processed. We applied together on same date, for same purposes, with similar documentation....We contacted both TTS and the Consulate, but there was no definite word except that the case is being processed. And We are scheduled to leave back this weekend... I heard that for some cases the processing times are unusually longer than 2 weeks. Anyone with such experiences?? I greatly appreciate if you could share your experiences.
And for those who are planning to do their stamping at Chennai consulate, better have adequate time (atleast 3 weeks or more) so that you dont run into last-minute hassles and tension.
