Tubercoloma epilepsy related issue.

My friend faced a health seizures in 2012 1st time used a course 20 months later without doctor permission he stopped the medication, in 2016 again he faced a seizures suddenly again went to hospital & he started using medication oxetol 450 daily 2, Two years he was taken Brain MRI'S, video EEG, ECG, blood tests etc all Reports are normal we are very happy Doctor told to stop the medication but friend was panic that's y he was not stopping even though he was all right. Now his age was 25 he have huge responsibility towards his family, He was scared if he stop the medication suddenly if same problem repeat again means he can't manage his situation so he was using medication till now Now my Question is Is he able to go abroad for masters with this medication Because few country's are not accepting epilepsy history background students . PLEASE TELL ME THE PERFECT SOLUTION TO COMPLETE HIS MASTERS IN ABROAD THANKYOU
