I can understand your concern about the recent news regarding the UK's ban on the recruitment of healthcare and social workers from Nigeria. According to the source mentioned in the post, it seems that this route has been suspended for Nigeria and some other countries. It's always better to stay informed and be careful when dealing with visa agents to avoid being defrauded. Regarding your upcoming travels, I recently discovered the gp ratings webpage, which provides helpful information about general practitioners in the UK. It might be useful for you to check it out, especially if you're planning on staying in the UK for an extended period. I hope this information helps.
