I came back from Calcutta yesterday evening.  Finally after all the troubles, we got the visa stamped at US Consulate. Visit was overall a nice experience barring some bad experiences with taxis drivers there. One of them took us 2 round circles over the area for US consulate which was just 5 minutes walk 

Stay in hotel Kenilworth was nice & comfortable however hoping Jet flight back to Bangalore via Hyderabad was too tiring. We also had an experience in Metro Train there on recommendation of Sujay, which was a good ride indeed (probably because of less crowd on Sunday evening )

Unexpectedly, at the consulate only few formalities were done on the name of interview. Nothing much the lady interviewer asked before taking the fingerprints and granting L1 / L2 Visa to me and Ritika. Looks like they are experts in judging the genuineness of a person ( a couple and a guy were rejected visas immediately before us).  We were really relieved when the lady said “You are all set...”.

Overall my experience in Calcutta was against most of those people who say that it is a dirty and congested city. I think it has improved a lot.

Cheers!!
