If you need to make a reservation to visit an immigration office in South Korea,
I think it is still better to create an account in the Hi Korea website. Just
make sure to remember, take note or not forget your account details as trying
to find your password through the site is a bit of a complicated process.
However, in cases that you reserved a visit through the website
as a non-member and need to cancel that reservation, here are the steps to do
so:
Go to the Hi Korea website. Close any pop-ups that appear,
and click reserve visit.
Click appointment reservation status (non-member) on the
left-hand side options.
Enter the required information in the boxes on the page, and
click confirm button.
A list of your reserved appointments will appear. Select the
appointment you want to check details of.
Details of your visit reservation will appear. Enter the
password you registered upon reservation of the visit, and click the cancel button.
A pop-up will appear asking if you will cancel the online reservation, click ok (or the blue button). A pop-up will confirm that the reservation has been
cancelled successfully. Click ok (or the blue button).
You will also receive a text message
on your phone that your reservation has been cancelled.
