i think the nearest location would be bukit indah.
there is cw3 bus to take u to jurong.

waiting time is 20min interval.
go jb custom then go sg custom. u need to drop down 2 times.
one trip probably takes 1.5hours (depends also on volume of ppl lining up )
non SG PR checkpoint is vyvyvy slow compare to SG PR checkpoint.

The average travelling time from bukit indah to jurong approx ~ 1.5hours

THAT ALONE will just land you in JURONG.
if u need to travel to your office destination, cost a little more time ?

--------------------------------------------
some ppl will save tat amount to money to stay in JB. (sacri time )
some ppl will jz rent room in SG. ( sacri money )

unless u ppl gt better pay in SGD then only go SG work.

i hv a fren working in palace of golden horses.
gt job in SG for only 1200SGD.
travel my motorbike cost SGD 4/day.

stay in SG share room SGD250/mth.

u ppl decide the conclusion.
