Are teachers culturally sensitive/competent throughout the world.

This was not the best question to ask because I could not find any sources to answer my question. I can only answer this solely on my personal experience. When I was younger I lived in Germany for a few years. The teachers were suppose to assist me with translating and making the process easier for me to adapt to the new culture. Unfortunately, I was an outcast and  all of my teachers throughout the few years failed to assist me. My older brother was going through the exact same thing who was a few grades ahead of me. I have heard of people studying abroad and having a great time but in my personal opinion the rest of the world is not culturally competent like the U.S. A good reason for this may be because the teachers have experienced the same students with the same culture their whole teaching career. Also teachers in the States have an better chance of coming across a different culture than other countries. I wish that I could have found some valid evidence to support my findings but I was unable to do so.
