I applied in Feb, 2004, from Thailand. And completed my medicals in Oct 07 and still waiting for CIC Singapore to reply. From what I hear the workload at the Singapore Visa Office is pretty heavy and the average turnaround of an application is 4 years. Yours could be much earlier, just my personal opinion.

Hi Dipkona,
Mike is right
About my case our medical done on Nov 2007. We waited 41 Months to receive the medical instructions.

Good luck!!!
