O/A on only good for one year if obtained from your home country then can obtain one year extra stay, can not have a further stay have to leave the country and get a new O/A or change to a Non O
The guy who posted on Facebook about his dealings with NK immigration must need insurance as he might have dementia he might have an overstay. He has two O/A’s over 7 years residency so with extensions it might give him a bit over 4 years stay. Does he really know what visa he is on? His overseas visa sounds O/A then he could not possibly stay 7 years on 2 visas. Did he really ask the right questions? Did the IO really understand him.? Or is it a bit of bull sheet by a stirrer?
