as to me, i didnt know also when or how am i going to have a case officer, but what i did was i send an email to Bangkok Branch and asked them, they right away replied and made me known the name of my case officer, however, it has been six months, i was just informed when i asked my case officer that my papers has not yet reached its time to be opened yet
no choice but to wait, i hope i gave u an idea that can help
