Looking for a job

Sorry but to be blunt you gave no serious chance of a job, especially  getting a work permit, as you have nothing of value (skills wise) to offer Malaysia (based on what you said). Your skills seem very specific  to Pakistan. And there are certain countries Malaysian immi seem to be biased  against.....

You could use MMH2 if you want to retire and have sufficient  capital.

Another possibility  is to open a restaurant, although  that's  a hard business for someone without  experience.

Maybe  some kind of import or export business to or from Pakistan is a possibility. Again best with experience. You will need capital.

Fareed, I dont think you have any chance. If government related office work is what you want to do, there is a multi-year waiting list of locals for those jobs. I cant imagine a foreigner jumping that queue.

As Nemodot said, your best chance is to find a local private company who wants to trade with Pakistan because you could be helpful for that, especially speaking the language. Start researching the topic of trade with Pakistan and very possibly there would be jobs in the import-export area.

And yes, you can also start your own company if you can meet the capital and other requirements.
