Working with Internationals in America or Abroad?

am a trainer at the Grand Canyon. We train and work with a large workforce of internationals for 3 month periods.

Does anyone have experience teaching, relating to, counseling, and communicating with international employees?

Have you seen a website with kitchen terms and translations? "Behind you....86ed"
What experiences and foux-pas have you dealt with in communication with internationals? Do you have tools and stories for basic communication? Do's and Don't of social interaction?

Let us build a working relationship of terms and helping hands. This is not a forum for racism and bias. Just the opposite, an international relations comittee.
