Not sure if the law changed, but for the 12 years I was on student (F1) and then work (H1) visa I had to notify INS if I changed of address. If you are traveling internationally frequently there was no need to separately inform them because you would do it on your entry form, but I've had to send a special form once when I moved and wasn't planning to travel for a while. This was about 10 years ago so things might have changed.
