Earliest option to get back passport

Hi,

I have my H1B stamping interview in chennai in March.

When is the earliest I can get my passport back if I interview on Friday?

Monday or Tuesday? What time?

I plan to travel back on Wednesday, so checking. Please help.

Thanks

The gap between visa Interview date and departure date from India should be as large as possible

One can never be completely sure about time taken by any consulate.

assuming you do not get 221 G, normally you should get passport in ofc by tuesday if interview was on previous friday.
