How long would it take to get a long-term UK visa now with a Dominica passport – or is it not allowed altogether?

I got my citizenship by investment a few years ago via my dad and now that it no longer offers visa-free travel to the UK, am I better off applying with my Dominica passport or home country passport? I’m from Ghana.

You are better off applying with your Dominica passport for a UK visa than on a Ghanaian passport. You can also apply for a long visa if you travel to the UK often.
