Thanks to the feedbacks received by some who left the comments in my blog, it appears that some have been approved already. Congratulations!
I made a call to an agency in Korea and they haven't heard anything from MOHW. It appears to me that MOHW is reviewing and approving the stacks of files one agency at a time. So if you haven't heard anything from your agency, just hang on. You will hear the good news soon.
My prediction is that by next week's end all the first batches of EPs will be approved. I am told that MOHW received all the EPs from January and February of 2012, and my guess is that by early April both March and April batches will be sumitted.
So if you have gotten the news that your EP has been approved, a hearty congratulations!
If you haven't heard the news, just hang on as they are still being approved.
I congratulate all of you ahead of time!
