When can I apply to extend my F-6 marriage immigrant stay period, and what documents do I need?

The reference materials do not list the F-6 extension timing and documents separately, so I will check the official sites.Note: the page lists F-6 as eligible for e-filing in one passage and as excluded in another (the list is ambiguous), so I'll avoid claiming e-filing availability.

Conclusion: You must apply before your period of stay ends. Check the general rules below for timing and documents.

📅 When to apply

• To stay longer than your permitted period, you must get extension permission before your period of stay ends.¹
• In-person applications are made at your local Immigration Office (출입국·외국인관서) (office or branch). You can book a visit up to 1 day before your expiry date.²
• If your visit booking date is 60 days or more before the expiry date, your application may not be accepted. In general, it is safer to start preparing 2~3 months before expiry. Check first by calling 1345.
• E-filing (HiKorea (하이코리아)) is available from 60 days to 3 days before the expiry date, not counting Saturdays, Sundays and public holidays. However, the notice is unclear on whether F-6 is eligible for e-filing, so you need to check on HiKorea.²

📄 Basic documents

• The common documents are the application form (Annex Form No. 34), passport, Alien Registration Card, and proof of residence address.²
• F-6 (marriage immigrant) has extra documents depending on the status. You may be asked for proof that the marriage is continuing and for the couple's income and asset documents. A specific list could not be confirmed in the materials.
• Check the F-6 documents in the guide manual by stay status on HiKorea.

💰 Fee

• The fee for extending F-6 status is 30,000 won. Fees for applications that have been accepted are not refunded.²

⚠️ Things to watch out for

• If your expiry date passes, you may become an illegal resident. If it has already passed, we recommend consulting an administrative agent (행정사).
