Which IT domain has more scope of Onsite Opportunities

I don't know if it's just me. I have been in IT field for more than 5+ years and in the same company. I don't have domain expertise in at least one domain and management is shuffling me between various non technical projects. Why I need your advise is , I want to jump into technical field or domain where i can see good scope of onsite opportunities. Kindly suggest me a domain(Non-Coder) which i can learn and move on from here. I have completed my Masters in computer application from Bangalore university.
