Enlish is considered global communicative language to people in the world. Especially, learning Engish becomes popular in Vietnam. Many English language centers have been flourishing well with thousands of students attending to get courses every night. That is a big business therefore many foreigners from US, England or from English speaking countries travel to Vietnam to get opportunities to work as an English teacher.
That is great when students can interact with them in practising English. Among the foreigners, a lot Vietnamese who was born and live in US or Canada who called Việt Kiều want to come back and devote in teaching English in language center.
A rate/fee per hour belongs to who you are. Obsolutely 100% native teachers usually get much more salary than Viet Kieu or Philipino, even Vietnamese teacher.
Why so? If it is compared the native teachers to Viet Kieu who have the same level, language fluency, academic training and qualified certificates, every things are equal but the salary is never the same. Just because we are Asian looking, we are not blonde hair or bright skin and the most importance is that Vietnamese parents or students enjoy studying English with a native speakers more than a Viet Kieu teacher. They believe that Viet Kieu does not speak English so standardly and fluently as the native speakers.
It is true when happened to my friend, a Viet Kieu. When a HR officer made a call to him and interviewed, everything went right. She was pleased at his American accents and decided to get him to the second round. When he came to see her at the office, after meeting and talking with him, she politely refused his invitation to be a teacher with a very simple reason: he is Viet Kieu. She told to him that her students did not like to study English with Vietnamese origins although my friend explained that "No no... I was born in America and I come back to work here." He was really surprised at her reply and extremely shocked. Now he got the job as an English teacher at a center and do tutor at his home but the lower rate than he expected.
I write this because I hope that once day even Vietnamese teacher or Viet Kieu would be treated well as the native teachers. They deserve to get the equal benefits if they are good enough in teaching English as well as high education with qualified certificates.
