Entry and exit from US

[blessed2]

Have a question. When I entered the US from another country on a visitor visa, they stamp my passport, but when I exit, nothing is stamped. Does that mean that their system have no record of when I left, only when I entered? Please help, thanks.

The airline collects your I-94 Arrival/Departure record and returns it to immigration officials when you leave.

those I-94 cards is the only way immigration can tell how long i was in the country?

No, the airline shares information about passengers too.
