No problem butting in Nick. You are most welcome. I can't answer for Vietnam courses or for visa arrangements, but I have posted some general guidance on choosing a course which may appear at the same time as this post - ( I'm having problems with formats on this particular board, and I've emailed site Admin about it). If you turn my guidance into further research with those providers in Vietnam, it might help you decide.

Although many TEFL providers offer employment as a 'sweetener' in their recruitment, I would wonder if the jobs they offer are those that have been rejected by others or are in some far-way place. I'm certain that I will be corrected on this if it's untrue.
