Day 1 @ Chennai VAC: took about 1.5 hrs, need to carry passport, appt confirm page and DS160 conf page, and of course a face and 10 fingers! Cell phone and umbrella allowed inside.
Narrow street, located on Kodambakkam High Road, Nungambakkam. Use Google maps or wisdom of cab/auto drivers. Nearest landmark is Valluvar Kottam (for non Tamil folks, pronounce it as val-lu-var ........ kot-tam), Note: VAC is not right next to it but in the area.
VAC is located inside the multi-storied white building, looks like it is in the final stages of completion, not a posh building but just a new building. There is a board outside but it advertises a Xerox center!!! (more on that later). Easiest way to locate it, is to look for people with serious faces but in formals or business casuals hanging around with a backpack or a thick folder, oh not to mention the freshly married women with makeup and mehendi/hena.
No need to come too early or dressed in "coat-suit" but people do. You will be allowed into the premises only an hr before your appointment time, even then you will be placed in a line within the building until your appointment time. Only the candidate is allowed inside the premises, "support team" has to wait on the street :-) I saw couple of babies (less than 2 yr olds) inside, no idea if the kids needed Visa as well or were allowed because they are babies, please check before going. Note: as usual there is no shade (other than trees) on the streets so your "support team" has to be rain or shine types. November is rainy season in Chennai
Backpacks (college style ones) are not allowed inside the building. Women can bring handbags/purses, I saw one guy get away with a satchel. Cell phones are allowed inside but has to be switched off once inside. In case you bring a backpack then some entrepreneurial Indians will provide you a locker for 50 bucks right before you climb the stairs or go up the elevator. I saw one mom was allowed to take water for her baby, so it looks like it is not TSA like security so if you really want to take water inside then please plan on having a baby few months ahead of time ....... ha ha ha
Once you go up, you will be put in a line until your time (about 50-70 serious looking people), then let into another floor, scanned for security, switch off phones. People wearing strange neck ties will check your passport and DS160. They WILL catch any mismatch and tell you to get it fixed before taking the picture and finger prints. Worry not, remember the entrepreneurial Indians I mentioned earlier, they will rescue you for Rs200 :-) Just go down stairs, tell them you need to update your DS160, they have PCs with internet connection and printers and will even help you in case you are paralyzed with fear of missing your all important appointment! In case you cannot afford Rs200 then step out of the building, go to the auto stand or any building across the narrow street and get it done for lower price. Oh you do need to know the answer to your DS160 security question or have a phone to wake up your son/daughter/significant other in US to ask them the place of your elementary school!!
NOTE: this last step will change your DS160 number, WORRY NOT, it is ok, no need to re-print the appointment conformation letter, just print the DS160 confirmation pg
Once the "half tie" people have cleared your data, you will go to another "half tie" person and they will print a sticker with bar code and put it on your passport, stamp your DS160, get a token number, join a short line, watch the TV screens for your token number or get reminded in a loud voice, walk to your counter (behind a white screen?!?), hand over passport and confirm pages, read mumbo jombo (actually terms of service type stuff), get picture taken, 10 finger printed, step away, read notice board for instructions on how to collect your passport and holidays, give a simple feedback on a touch pad, push a small button, open a big door .............. bye
--------------------------------------------
Day 2 @ consulate: 2 hrs (most of it standing in line inside), mine was H1B extension, need to carry passport, DS160 conf page with the blue stamp from yesterday, I797, loads of support docs that you may need. Umbrellas are allowed inside the consulate but no cell phones (more on that later). Backpacks, lady's purse, satchels not allowed inside.
Again US Consulate is not designed to accommodate candidates ahead of time or the "support team". November is rainy season in Chennai. You need not come 15 min before your appointment but it is impossible to time it so if you are early then be prepared to stand on the sidewalk. If you have a cell phone (who does not, in 2017) and have no "support team" then entrepreneurial Indians will escort you in the opposite direction, down a dark subway, up on the other side of the main road, to a tea stall/corner shop, where another entrepreneurial Indian will take Rs200 for storing your phone and the escorting Indian will take Rs100 as a reference fee, walk all the way back, DO NOT rush, your place is not taken, just tell the security guy/gal you were there earlier.
There will be 2 or 3 checks of your passport and Ds160 confirm page with blue stamp. Yes they will ask you to open your all important document bag even when it is pouring like hell.
Once inside, there is security scanning, then another check of passport/confirm pg, then another check, then 1st line, then a counter for finger printing, then 2nd line, then VISA INTERVIEW. It is ok to smile and exchange pleasantries with the Visa officer, poor fellow has to talk to 100s of serious faced people.
Visa questions:
Name of Employer?
Your highest qualifications?
Job title?
What type of job do you do?
Client site or not?
Job location
Salary?
Congrats, ur visa has been granted, have a safe journey :-)
My only gripe: interviews in native language were given preference over English interviews, about 50 people had to wait (standing) for 45min before we got our chance. It could be because we were the first appointment of the day. It was ok because most of the native language candidates were old people or people with babies.
