My sister is more than 18 years old and is a dependent of my parents due to the fact that she has partial hearing loss since birth and she could not learn to speak. She didn't receive any formal education however she is natural born painter and artist and does incredibly good paintings. She also did a 2 years art course to improve her paintings. In IMM5669E form I couldn't found a field to mention this so I left it as blank. Is it a mistake? Shall I inform CIC now? In our case file is already transferred to London Visa Office and Medicals have already been done. What shall I do now?
