I am physician who graduated from an overseas university. I have no plans on returning to SG other than for vacation, but kept my SG passport.

Given that I finished NS as an LTA, I believe I can be called back anytime before the age of 50? If I get called back for NS reservist, do I have to undergo the full MOCC?

Can I avoid disclosing my physician status? Any benefits for disclosing?

Thanks in advance!
