I had my visa interview on 5th of June. Went well overall and am happy and relieved that I got this out of my way. Though a lot has been written about the visa process per se, I would like to add my comments on the subject. A couple of points to note for potential applicants-
1. Fill up the forms DS156, 157 and 158 in advance and revisit them for mistakes a couple of times before taking the prints.
2. Dont forget to pay the SEVIS fee of 200 $ . It is not explicitly mentioned in the vfs site.
3. For the chennai consulate, you will mostly have to schedule an emergency meeting as the regular days are washed off
4. Keep your documents of funding ready-either through loan or fellowship or funds from self and family .
Questions asked-
1. Which university?
2. When did you pass out ?
3. Where have you been working?
4. How are you funding your studies?
If the documents are in order, this should just be a formality. All the best.
