I am a PGY-7 Registrar in Singapore, having finished my compulsory government service. I graduated from UM, having taken my STPM with 5As in the last millenium.
I am currently pursuing a PGY-2 position in Internal Medicine at a top center in the US; I am only getting in by virtue of having my MRCP (UK) and my USMLE Step 1 through 3. I will be 32 when I start off in the States, and I require another 6 years at least to complete my sub-subspecialisation.
Please be aware of the sacrifices you'll have to make if you choose Medicine.
Words of warning, if you come from a lesser university than UM and try for the USMLEs, you will likely get a crap center in America. I tried 3 years ago, and have persevered by taking my MRCP. So don't give up.
Mind you our country slips farther back into the dark ages with time, and you will be competing against the best Indian universities (like AIMS, Aga Khan). Do not underestimate them, they have a fantastic network in the US, and they will wipe the floor with most UM students, Bumiputera of otherwise....
Oh and is SG meritorious? I think you best discuss that with your friends or relatives who have been there. The grass is always greener.....

Just filtering through the chaff in this forum.....

Hi sofaking, why do you want to do your "sub specialisation" in US for another 6 yrs when you can complete it in 3 yrs times in spore? u have relatives in US or u r into very competitive fields like cardiology.

and to the rest of the forumners, it's best not to jump around different countries as they have different regulations, and sometimes you have to start just like a fresh graduate in a place that doesn't recognise your qualifications and working experience at the place you previously worked at.

Hmm, A Malaysian who qualified for Unimas in 2007, and who holds his/her medical school (NUS) in high esteem, to the point of being condescending of others. Also highly idealistic. You should be M3 by now. Let's see if you can trace me before I can trace you..... Oh, and enjoy your residency and bond
