the thinking of overseas grad is better than local is more towards them gaining experience of being independant and mixing around with people outside their usual environment...indirectly improving your social and communication skills...

sadly its not true for msians because many overseas grads go there and mix with their own kind...like a mini msia...some even come back worse than before they left...so in my opinion its too subjective...

at the end of the day when i interview someone...ill hire the one with better communication skills and positive attitude...where the degree comes from doesn't matter much...
