How to get permanent residency in Abroad? :-?

Each country is different. Some are easy and others impossible. If they have a consulate nearby, you should make an appointment and visit it. If not, then go to their official websites and print out the forms. You can apply for jobs, but be sure to tell them that you will need work authorization. Many companies will not want to be bothered and will not consider you, but you could find one that does and will do everything for you. You won't know if you can migrate unless you apply.
