Well ,every experience matters when it comes to immigration, you can't make them believe that H&C is like a walk in the park. Few things has changed , but not all. Your statistics on approval rate is not that much, but its has improved from the all time low that it use to be. Every case is different and it has a lot to with the supporting documents you have to prove your case ,and also the officer's discretion. There still people that are not in this forum that are still 2018/2019 that still don't have AIP yet. Even the ones that wasn't so lucky to get deferral from Removal order.
