What should I do if the Immigration Visit Reservation is fully booked?

If your immigration visit reservation is fully booked, do not assume that a same-day walk-in will be accepted. First check HiKorea for cancelled reservation slots and confirm whether your exact application is available as an e-Application. If neither route is available, call 1345 or the office with jurisdiction over your address before your stay expires. A Statement of Reason does not guarantee emergency reception or approval.

1. Check Whether Your Exact Application Is Available Online

HiKorea offers e-Applications for some immigration services, including some stay-extension cases. Availability depends on the exact service, residence status and case. Do not assume that every E-7, D-2, F-2 or F-6 extension can be completed entirely online.

Check the live menu: Log in to HiKorea and look for your exact application under Petition Application → e-Application.
Follow the displayed cutoff: Electronic applications must be submitted before the service-specific deadline. Official guidance commonly sets an earlier cutoff than an in-person application, so do not wait until the expiry date.
Check the displayed fee: Do not assume a universal 20% discount. Pay the amount shown for the specific e-Application and confirm any exemption or reduction in the current guidance.

2. If Online Filing Is Not Available, Act Before Expiry

Keep checking HiKorea for cancelled reservation slots. Stay extensions can generally be prepared months before expiry, so reserve as early as the system allows rather than waiting for the final week.

Call 1345: Give the adviser your residence status, expiry date, jurisdiction office and exact application. Ask which filing route is currently accepted.
Contact the jurisdiction office if instructed: Follow the office-specific direction you receive. Do not travel to another office simply because it shows an open slot unless HiKorea or 1345 confirms that office can accept your case.
Consider a registered immigration agent: If the application may be filed through an authorized agent, ask about that route. Availability and documents remain case-specific.

3. Do Not Rely on a Guaranteed “Day-of” Walk-In

The official visit-reservation guidance says that immigration petitions generally require a reservation and that an unreserved visit may not be accepted. Limited exceptions exist for specified filings or applicants, but a fully booked calendar by itself does not create a guaranteed emergency ticket.

If your stay expires today: Contact 1345 and the jurisdiction office immediately and follow the official instruction for your case.
A Statement of Reason is not a filing right: You may be asked to explain the circumstances, but carrying a letter does not guarantee reception, extension or waiver of consequences.
If the stay has already expired: Seek official guidance immediately. Do not assume that paying a fine automatically resolves your status; the response depends on the facts and immigration decision.
