If you need to get a work visa in Singapore, don't do it yourself: use an agent like One Visa
The One Visa Team just secured the renewal of my Employment Pass (EP) and my wife's Dependent Pass (DP) within a week of my obtaining confirmation of my education credentials. My wife and I have used One Visa since 2010, when they obtained an Employment Pass for me, Dependent Passes for my wife and son, and a Work Pass for our long-term domestic helper. Whether you are an entrepreneur trying to decide if/how you can legally live and work in Singapore, or a Director/decision maker of an established company that is considering whether to establish an office/base in Singapore, Cheng, the founder, and his team can help.
