Right, instead of talking to people here, I would suggest you (
Miss bee) read through the government website regarding the language test requirement. There is a lot more information that not necessarily accurate out on the net/forums. I posted references/links before, you can look it up. Some of the rules did not indicate you need to submit a language test, but all the rules did not say what will happen if you submitted something expired or invalid. If I were you, I won't take this risk to try and see what will happen when applying with invalid documents. Stick to the game rules. If the rules did not say you need it, then you don't need it.
If the application get denied, you can try to appeal the decision with their rules but definitely not what people said.
