Hi everyone, I'm from Vietnam ( a developing country as you know ). I have graduated since August 2015. Bachelor's in Physic ( Nuclear Physic). I joined many social activities and also was a students' leader in my department. I did 2 researchs during my university. Now I really want to make my dream true that I can be a research assistant in the field. Could someone suggest what I have to do next or let me now more if I have to have an IELTS or some of certificates? Thanks all.
