I had this opportunity to work for a company in Singapore but I am not sure yet if I will accept it.

I was looking on a map how Singapore looks like and it is of course quite small. So the question came to mind whether it would be practical, safe, or otherwise feasible to live in Johor Baharu (Malaysia) while working in Singapore?

Does the border crossing between the two countries take a long time? Are there any options for faster processing at the border (like the U.S. Global Entry Program)?

The office would be somewhere near the Dhoby Ghaut MRT station. I would not have my own a car as I am not sure I want to go into debt (in case the job does not last, etc).
