If I switch to E-7-4 or another status, what happens to the National Pension contributions I've paid so far?

The E-8 in the National Pension Service's guide refers to the previous training and employment qualification. Currently, seasonal work E-8 is not eligible for the lump-sum refund payment for each qualification. E-9· If you have a history of joining as an H-2 and are planning to change your status, ask the National Pension Service at 1355 to see if you can still receive it after the change. Ask before changing your eligibility.
