H1B stamping in Mexico- Experience.

[patilrahuld]

I am going on a business trip to Mexico and plan to stamp my H1B while on a trip at Monterrey.
Can anyone share their experience of visa stamping in Mexico (especially Monterrey)?
Can i collect my passport the same day of visa interview? I believe it is a 2 day process - day 1 bio metrics and day 2 - visa interview?
Please advise.
