If a teacher is a non-native speaker of English, can he get an opportunity to teach in a reputed international school? How?

English is an international language and is therefore taught in many countries around the world. If the mother tongue is not English, English may be the second language (speaking Languag). So non-native english speaker can be able to teach in an international school 

There is possibility that they can teach in a reputed international school only if that school offers the same language that a teacher speaks. If not then they will not be able to get an opportunity to teach in an international school.

NO HE CAN'T , BECAUSE IT WILL BE A BIG PROBLEM TO COMMUNICATE WITH THE STUDENTS
