Conversely Class C and D Control in Australia is very " ICAO" and I/ve never in any single nteraction had any doubt whatsoever what the instruction was. The traffic intensity is is much less of course, and I suspect International flights into the USA just adopt the local lingo with USA destinations - this is easy to do if you're are a native English speaker, but its a definite safety issue for non native english linguists.
Emergency requests are often best best made in plain speech.
