Hello. Thank you for your reply.
* I was never physically arrested, detained or incarcerated at any time for this offense.
* The offense was being found guilty of having THC in my system. The active ingredient in marijuana. I admitted to the offense and was fined by the university court and told to do tests for the duration of my studies, which I passed.
* I did not appeal to any higher court as this was an university matter and it was not severe. I was NEVER found in possession of any marijuana. I took marijuana at a party only once.
* I still received a police clearance certificate from the country of origin which proves that I do not have any criminal record. An university court as I far as i know is an institutional entity and doesn't fall under any judicial category in the country of origin. I may be wrong, but since I received a police clearance, I am not sure exactly what the issue would be.
