Intercutural Communication_I need your opinion

Hello!

I am currently getting a Masters in Developmental Psychology. For a very long time I am fascinated with other cultures, and I would like to specialize in intercultural communication. My idea is to specialize in one or two regions (here I have in mind Singapore and Malaysia and/or Romania) and conduct cross-cultural communication workshops to a target population I have yet to determine- I am thinking something geared towards mental health personnel, although I am flexible with this. Ideally, I would like to integrate my background in Psychology with my interest in other cultures. I am also interested in research and I have research experience pertaining to psychology. I was wondering if you could guide me as to what program I should apply to given that I am in the process of getting my Masters in Psychology. I am not sure to what extent it would be indicated to apply for a Masters in Intercultural Communication or if to go for a PhD program. I would eventually like to get my PhD. What are some programs that you recommend? Should I seek employment in the field prior to applying? Or is this not a must? Thank you.
