Use it all the time here in the US. DOmestcially (121.619) is taught as the 1-2-3 ruel (1 hour before and after arrival, 2000; ceiling, 3 miles vis) and we have aexemption from the FAA to reduce to 1000' and 2 miles vise if a cat 2/3 approach is available.
International (Flag) is pretty much the same most places as long as your scheduled under 6 hours. Again, use it all the time. Most carriers do the same.
