Late Stamping interview questions and answer approach

Hi All,

I have a query for H1B visa stamping interview. My petition got approved this January 2017 but I didn’t appear for stamping till now due to fear of increasing number of 221g and visa rejection.

I have internal project as per documents and I am in India since then. This is my first H1B stamping interview.

Its been more than 10 months, now if I go for stamping interview I might get this question -

“Why are you coming so late for interview when petition was approved in Jan”

How should I best answer this question and what things should I keep in mind for preparing for interview.
