do U.S. officials track your absence abroad..

as a green card holder i wondered if U.S. officials could see in the screen when you last left the U.S.?
THey always ask when was the last time you were in the U.S. so could they actually see your last departure?
I read once somewhere that they could only do this with U.S. citizens??
Any idea?

thanks!

At this point: any time you leave the US by bus, train, boat or airplane CBP/USCIS will know when you left.
If you leave by car via MEX or CDN it depends on whether the car is registered in your name or a relatives name that can be linked to you, whether the Mexican or Canadian border guards will check your documents and enter the data into a data base...so, I would say, chances are US authorities even in this case might know when you left the country

Why should it matter if they do? Are you trying to spend too much time outside the United States? (too much to be consistent with keeping your green card).
