Go to your nearest Korean embassy and apply for a G1 visa.  If you are in Korea now, you can find a job in construction, chicken farms, or car part factories.  Usually people from your part of the world tend to work with exporting car parts to the Middle East and North Africa.  These jobs are usually found around Ilsan, Ansan, or Dongduchan.  If you go to Itaewon and go to the local Turkish kebab places you can ask around and you will get suggestions as to where to find work.  Factory jobs are pretty easy to come by so you shouldn't have a problem getting those quick.  Unfortunately you might have to move further out of Seoul to get them. 

As far as an English teaching jobs, those are only open to people with Bachelor's degrees or higher and those who are from native English speaking  countries (US, Canada, UK, Australia, South Africa, with a few exceptions for the Philippines but not from the public school realm)   

THX FOR REPLAY
im in algeria i have been never go out before
i cant get visa travel or visiting because imnot working
i need visa work if that possible
i have no other ways

Well you do need to have some money saved up before you come to Korea.  Not a lot but at least $500.  And go to your local Korean embassy in Algeria and try applying for a work visa from there.  Otherwise try searching the internet for Algerians in Korea.  There you can ask on those forums if anyone would be willing to sponsor your visa so that you can work in Korea. 

Just come to Europe and live on 1000 euros a month free welfare +free housing till you die. There's a widely reported case of Eritreans going back on holiday each year with their holiday welfare check in May while claiming Eritrea is too dangerous for them to return to. They will forever stay on welfare while playing fat cats back home, so why wouldn't you?
If you live in a big city you don't have to learn the language either, most people/ neighbourhood stores speak Arabic nowadays and in a few years the majority of people will be muslim so you'll have friends in no time.

Really, so many Algerians are already doing that, why do you want to go to Korea? They will not give you any free allowance while you apply for asylum as an economic refugee as you would get in Europe. Just burn your passport on arrival and say you're from Afghanistan so you cannot be sent back as Algeria is a safe country.

Wow, a guy asking how to legally come to Korea and work and you just shit on refugees, ethnicities and religions all at once. Congrats man, I never thought that was even possible. Plz tell me more about how you moved to another country.

Does it mean the poster in question is wrong?

Plz tell me more about how you moved to another country.

I think the Guns, germs and Steel theory https://www.pbs.org/gunsgermssteel/ has a lot of merit to it. It is wholly unfair that only a tiny fraction of the world's population is entitled to so much of it, merely based on the luck of the draw of where they were born. Europe is in decline and slowly building walls as Ancient Rome had been in its final era. To anyone still outside these walls wanting to enter, I say hurry. For myself, I might eventually move to Canada one day.

How about you? How were you allowed entry to South-Korea? Oh, you don't say, you could speak English? My, my, what a wonderful accomplishment indeed. 

Mate, we're all banking on our white privilege one way or another, no need to act so sanctimonious when I point out that there are millions of people living in absolute squalor only because some Europeans raped and pillaged their entire continent.  They are owed their dues as far as I am concerned, let them have Europe. I will live somewhere in a cabin and do those outdoorsy things Canucks seem to enjoy. 

I'm talking about Europe's colonial history as a justification of economic migration, he singled out Sweden only because it has accepted large numbers of immigrants while offering a high standard of living compared to Italy for instance, where people have to work themselves to the bone for a meager 5 euros a day living in makeshift shantytowns...

Then you segue into a completely unrelated direction which is helping the op how?

I am more than happy to enter yet another endless discussion on how Europeans view UBI and socialism but perhaps best not in this thread. I just think it is unfair that a US citizen can travel around the EU freely but an Algerian man like the OP cannot, simply based on him being born just a fraction too far south of the EU border.

All (wo)men are born equal.
