I am a single Indian national currently working in the US since April
04 on H-1B status. Prior to that I attended grad school in the US for
2 years. I graduated and started working on my OPT till I got my H1-B
approval papers. I have a F-1 stamp on my passport and would like to
change
that to H-1B during my next visit to Mumbai, India. I would like to go
in the next 2~4 weeks if possible. What are my options? Also?

1.	What is the next earliest available date at the US embassy in Mumbai.
2.	Which forms if any do I need to fill out?
3.	How much does the process cost and what are the accepted forms of
payment, where do I pay?
4.	What are the documents I need to bring along to help ensure a quick turnaround?
5.	How long does the process itself take?
6.	What are some common mistakes and other general information?
7. 	I have heard that I can do the stamping in Canada or Mexico
faster. Is that correct? If yes how does it work?

This is a clean case without any complications so it should be fairly
easy to find info on these.

Hi VKJ,

this site should be where most of the information can be found:
