Do you think they qualify for a dependant visa? Have you seen the new rules? If they apply and are refused, they will find it very difficult to get another visit visa
You can apply to join a settled person in the UK if:
You need long-term personal care to perform every day tasks, such as washing and cooking.
The care you need is not available in the country where you are living, either because it is not available and there is no person in the country where you are living who can reasonably provide it or it is not affordable.

With regard to long-term visit visa:
Short-term and long-term visit visas
A short-term visit visa allows you to come to the UK for a maximum of 6 months (or a maximum of 12 months if you are accompanying an academic visitor).
A long-term visit visa is valid for 1, 2, 5 or 10 years. The application fee is higher than for a short-term visit visa.
If we grant you a long-term visit visa, you are allowed unlimited entry into the UK for the time that the visa is valid, but for a maximum of 6 months for each visit.
We recommend that you limit your stay to the period stated on your visa application. If you spend long periods in the UK as a visitor, our officers may doubt your intentions.
If you breach the conditions of your entry to the UK, we may ban you from returning for up to 10 years.
If you apply for a long-term visit visa, we consider:
whether you can show a frequent and sustained need to come to the UK (such as family links or an established business connection);
whether your personal circumstances are likely to change significantly while the visa is valid - so you should give us as much evidence as possible that your circumstances will remain the same;
whether you have shown that you can support yourself in the UK without public funds, and that you intend to leave the UK at the end of each visit; andyour previous travel history as shown in a current valid passport.
You should think carefully before applying for a long-term visit visa. We may refuse the visa or issue it for a shorter period than you have applied for (if, for example, the evidence that you provide does not support a long-term visit visa application, or does not meet the visa requirements). If we refuse the application or issue the visa for a shorter period, we will not refund your application fee.
