I have been living in Korea for several years and want to apply for permanent residency (F-5 visa)?

Permanent residency (F-5) is achievable but has real requirements, and it is less scary than its reputation if you meet them. The common route is having lived in Korea continuously for at least five years on an eligible long-term visa, though the exact period and conditions vary by category: marriage-visa holders and certain high-income or high-skilled applicants can qualify faster, and a points-based route exists for others. Across most paths, the core requirements are a stable income above a set threshold (often benchmarked to a multiple of national income), a clean criminal record, proof you can support yourself, and evidence of Korean language and social integration, typically by completing the KIIP (Korea Immigration and Integration Program) or reaching a required TOPIK level.

You apply at your local immigration office with your ARC, income and tax documents, proof of residence history, the language or integration certificate, a criminal background check, and category-specific papers. Processing commonly takes a few months, sometimes longer. Is it as hard as people say? For someone with a stable job, clean record, five years here, and the language requirement done, it is very attainable and mostly a paperwork-and-patience exercise; the parts that trip people up are meeting the income threshold and finishing the KIIP, so many people start the KIIP a year or two ahead. F-5 lets you live and work here without visa renewals, a big quality-of-life upgrade. Check the current requirements for your category on the Hi Korea site or with 1345, since thresholds and the eligible-visa list get updated.
