I didn't use the Jobs Bank as I didn't intend to hire a foreigner. However, I couldn't find a suitable Singaporean. If I decide to hire a foreigner now, do I still need to advertise on the Jobs Bank?

Yes, you must advertise on the Jobs Bank if you intend to hire an EP holder.

Advertising on the Jobs Bank will help you extend your outreach to more job seekers, and may enable you to identify a suitable Singaporean candidate as you had originally intended.

Regardless of the circumstances for hiring an EP holder, you must advertise on the Jobs Bank for at least 14 calendar days before you submit an EP application.
