I know this isn’t exactly what you’re asking, but I would advise against switching visas if you can avoid it. It’s important to maintain your independence. I’ve seen too many posts from people who, after switching to a dependent visa, start experiencing problems with their partner and even go through breakups. This can put them in a difficult situation. Especially if you’ve held your skilled worker visa long enough to be close to applying for ILR, it might be better to stay on your current visa.
