Well, there are two nurses in Singapore who hold PhD's from
overseas universities. 
I will continue being a nurse - I love clinical nursing.
I wouldn't want to be in Nursing Admin though,
because I won't be able to participate in patient care anymore if I
were to choose that route. I want to continue to hone my skills and
become better and then hopefully, be good enough to guide the
newbies who enter ICU nursing. 
Only thing I cannot foresee happening, is remaining here in
Singapore. Our locals do not appreciate nursing as a profession, on
top of that, the remuneration and staff welfare is really miserable
and leaves too much to be desired.
Nobody wants to be treated and talked down to like a
maid, and nobody wants to work for management who doesn't support
them when patients and their relatives become unruly and
unreasonable. That's why there are more and more locals leaving for
overseas hospitals, and nowadays, it's no longer just the staff
nurses and senior staff nurses who leave - even the seniors, whom
we call 'Sisters', are leaving too. 
By the time the higher-up's wake up, they'll realise that the
exodus of trained talent would have left a gaping void.
