Departure stamp at US Airport

[virgopal]

While returning from Chicago during my first visit to US,I find the departure stamp is missing in my passport.The I 94 slip was taken back by Air India staff at Chicago check in counter.
However arrival stamp is put at Mumbai airport.I don't have any boarding pass stubs etc.
Will there be any issues during my next visit now?

There is no departure immigration check ( hence no stamp) in US.
So you are fine.

If you did not overstay your date on your I-94, you have nothing to worry.
