Guys,
I am just sharing my experiences thus far. The information is not presented correctly on the website but its somewhere there.
1) You are allowed to reschedule it once, after that you have to cancel and re-book the appointment
2) One reader has said no dates available in Nov/Dec. Its true, in Chennai next available dates are in Feb 2006. But, when someone cancels an appointment, then I guess you can book it. Which depends on your luck and also how soon you see it.
3) For people going from here on H1 and want to return back for work, you can schedule an "Emergency Appointment". You can also schedule it in any of the four consulates
4) The website says, H4's who were already in US and gone to India for vacation can go to any of the 4 consulates. This is what I am trying for my wife now. Booked in Delhi consulate, will let you guys know how it worked out
5) IMPORTANT: When you get the receipt#, you can logon to the website and create the applications (DS-156/157 and petition details) and save it. Then you can book your appointment whenever you like. This will be beneficial for people who are wanting appointments in Chennai. It takes atleast 1.5 hours to fill all those apps. and if you have it ready, you can book a date when its available
Remember, when you create an application it would ask
"resident of India" or "An Indian citizen resident in the US"
If you choose the second, then you have the choice of choosing which consulate. Please see the link below, where it describes what "resident" means. Scroll to the end of the page
http://www.vfs-usa.co.in/ApplnForms/RulesAndFees/ConsularDistrict.aspx
If you choose the first option and enter the resident state, then it automatically chooses the consular district for you.
6) Also, when you are trying to confirm an appointment online, please choose a PC that has Acrobat 6.0 higher installed and its connected to a printer.
7) When you are filling DS-156/157 and saving the form, a printer/acrobat is not necessary. Don't print the form after you fill it online. Does not print that well.
8) After the appointment confirmation, you can print the forms, download it to your hard disk. There is also an option, which would email you the link from which the documents can be downloaded.
If I remember anything else, will post again.......
