Can I live in South Korea as a foreigner?

Excuse me, I am a foreigner and I am considering relocating to South Korea. Could you please tell me if it's possible for me to live in South Korea as a foreign national? I'm interested in understanding the requirements and process involved in obtaining residency or a visa, as well as any specific regulations or restrictions that might apply to foreigners residing in the country. Additionally, I would like to know about the general living conditions, job opportunities, and integration process for foreigners in South Korea. Thank you for your help!
