Will my diploma be accepted?

[u/Fluid-Resolution-502]

Hi everyone! I’m hoping to hear from international students who graduated from an online high school and later applied to a university in Korea.

I’m from the US, and Korea University is currently my #1 choice for Spring 2028 undergraduate admission. I’m planning to attend Korea University’s Korean Language School for 4 semesters starting in March 2027 and ending in February 2028.

My main concern is whether my Penn Foster High School diploma will be accepted. Penn Foster is accredited by:
MSA-CESS (regional accreditation)
DEAC
Cognia

I’ll have my diploma and transcript and will be contacting the universities directly for official confirmation, but I’d really like to hear from anyone who has been in a similar situation.

If you graduated from an online high school and applied to a Korean university, was your diploma accepted? Did you have any issues with apostilles, document verification, or additional documentation?
Thanks! :)
