... a family member asked if he could fork out $100,000 in compensation. This figure, said the family member, was based on a graduate's $1,000 starting pay for the first year, plus an increment of $500 every month starting from the second year, plus bonuses and unpaid leave.

Currently, I don't think even 1 year would stand much chance of getting approved, let alone 6 months. You should have a look at the Singapore Expat forum to get an idea of the current situation, I reckon they have a fairly good discussion forum on PR-related matter.

And the above, is simply assuming that everyone here is Msian Chinese.
