In diving with internationally trained divers I have only had a few inconsistencies:
Other than that, most signs seem rather universal, except for skill signals, but those are only on training dives with extensive briefings.

- Apparently, in France the surface OK signal (clenched fist on top of head) means out of air/low on air as opposed to clenched fist on the chest or cut-throat.
- air pressure, aside from bar/psi problems. I was trained to show 1 finger for every 100psi (one per bar), but this leads to counting problems, especially with new divers who are narced. Some people use OK for over 1/2 tank and fingers for less or various other methods--fingers on chest/arm for 1000s or vertical/horizontal fingers
