I have changed that too just now, as I got nominated on dec15th, but still that 600 is not added.Before receiving nomination and after NOC2021 TEER change ,we had updated our profile with TEER codes . After receiving nomination with 4 digit NOC code , we changed all NOC code fields in our EE profile to 93888 without any issues.
how long did it take for you for that extra 600 to be added to your profile?
