I do not think you can find a room with SGD 500 around jurong east MRT, try to look in Jurong West (no mrt, but quite convenient as there are many buses) or lakeside mrt... if you want cheaper, go pioneer, but there a lot of unskilled workers... if you know what i mean...

Food wise, every few hundered of m, normally will have a food court or small food court...

Where is your office located at? IBP Jurong East?

Yes is around the budget, bear in mind normally you will need to stay with the house owner... pros and cons la stay with owner..

Bukit batok is cheaper i guess.. i'm not sure about there, but quite convenient, come out mrt already a shopping mall...

NUS area - clementi you mean? one of my favourite place, lots of facilities and nice food to eat... if you want to stay a location with food, i would suggest you look for a place near the clementi market, but not very near to mrt, try to check whether any buses passing by there to your office...

In my opinion, Jurong East is convenient, but lack of nice and cheap food (maybe i did not explore enough)... i prefer clementi better.. haha...

it's ok, as long as your office is not at those industrial areas, buses and mrt are quite convenient.

Singapore very hot geh, those days I thought of walking here and there also, but now if have bus take bus, if have mrt take mrt, and if really fadup take taxi once a while... haha.. anyhow sure can save in singapore, if you can't save then you must be a big spender... haha..

unless you are fairly very experience in this field, if not it's kinda difficult to get a job in this sector for a foreigner.

Singaporeans like this job field.. so competition will be higher..!
