we have been advised by an agent that we are likely to get turned down for a visa because our 3 year old son is disabled. He has global developmental delay and autism. He cannot walk or talk yet but is on his way to learning to walk. He is not on any medication and has no need of medical help apart from speech therapy and physiotherapy which we provide. He does have a statement for educaional needs. Just wondering if anyone else has been in similar situation and have you any advice?
