I have visited Chiangmai many times and wish to apply for a “O-A” Non Immigrant Visa and am an Australian citizen currently living in Brisbane. I am presently awaiting legal matters to be settled and am wondering if I sent application papers to the Thai Embassy in Canberra and am approved, how long after issuance of visa, do I have to travel? Also, there seems to be a lot of paperwork involved in the process and am concerned that matters may be delayed if I make one small mistake filling out paperwork, I may have to resubmit. Could any Aussies please enlighten? Thanks!
