by law, one must registered as a graduate engineer after graduate to be work as a 'legal' engineer in MALAYSIA. therefore, if one is not registered, then he/she is working as an 'illegal' engineer.

of course lah, in malaysia, nobody really enforce 'legal' o 'illegal' engineer. even some company (especially contractors) never bother if the engineering degree is qualified o not...

but i think Engineers Act do have a clause for oversea professional status... not sure oso. mb somebody can share info?
