how could i go abroad

It really depends on where you want to go.
If you want to go to some Western,developed countries,the best way is to study abroad.Since you don't have a good background in education and don't have enough money to go,the chance of getting a scholarship in those countries are really scarce.Maybe you don't want to consider study abroad then.
Another way might be that,you need to be working for a multinational corporation,and then somehow transfer to the offices abroad.But this requires you to have good communication skills in the language of the country you are going to.And you definitely have to comptete with others.
