I think they all should do. Doctors in the Philippines are trying to be a nurse to be able to go abroad and work as a nurse as they couldnt use their professional degree as they need such and such!
They have studied long enough for 10 years in the Philippines to be a Doctor. But going abroad they need to study again and take loads of english and medical exams! Its not fair.
I trust the Filipino Doctors and Dentist than those foreign ones who doesnt even know how to speak english properly. Filipino doctors are much much better to be honest!
