i have a friend pursuing E&E in UM is having intern in Jurong Shipyard, Singapore but i dont know how did she apply for it.

that's the reason i mentioned ' i'm not sure' 

let me list down a few things that employers are concern when taking in internship from overseas student.
1. they need to apply work permit for you in-order to let u reside in Singapore. Applying work permit usually take around 1 month time.
2. applying a work permit needs to go through a medical screening (fees paid by employer).
3. why bother hiring intern from Malaysia when they have so many student in Singapore it self?
4. the student might have home sick or during festive season where we need that person to work, 99% that foreigner sure not going to work because the distance of their hometown from the work place is too far.

If u manage to get an internship in Singapore, i would say that 99% of them got connection in that company and another 1% is lucky and mayb the nature of job of the company does not match most of the local intern's criteria.

PS : with Singapore GE is just around the corner, MOM (Ministry of Manpower) have tighten the rules in approving a work permit, Spass and employment pass. There are a lot of other forumer's work pass application got rejected and bare in mind, they are working full time and not only intern. So in other words, even u passed the employers interview. The SG gov might not accept you as well. Instead of going through so much hassle, why not finish ur intern in Malaysia, then only start looking for a Job in SG after you graduate.

obviously those companies come to UM to seek candidate for intern and possibly permanent job.  they do have good connection with the lecturers literally. one of them are micron singapore
