It doesnu2019t actually work this way that you can roll up to Singapore and apply for a work permit.In Singapore, Work Permits are linked to the company who employs you and so you need to secure a job first. Once you quit or are fired from a job, you lose the permit and any permission to remain in the country (of course there is a grace period for you to move out).Doing this from abroad is very possible as there are a lot of foreign employees in Singapore so its not an unusual practice.Alternatively, you could enter as a tourist (with evidence to suggest as much) as search for a job whilst in the country, provided that you do not overstay your allotted time (varies depending on which passport you are holding). However, once youu2019ve received a job offer, you may need to leave and the re-enter the country with documentation supporting your job offer that the you can be appropriately given a temporary entry permit by immigration whilst the MOM processes your E/S-Pass.
