These are the requirements if she wants to apply for permanant stay
Can parents, grandparents and other dependent relatives go to live in the UK?
If you are a widowed parent or grandparent aged 65 or over, or parents or grandparents travelling together and one of you is 65 or over, you may qualify if:
* you are completely or mainly financially dependent on children or grandchildren living and settled in the UK
* you have no other close relatives in your own country to help you
* your children or grandchildren can support you without needing help from public funds, and
* your children or grandchildren have enough accommodation, which they alone own or live in, where you can live without needing any help from public funds.
If you are a parent or grandparent under the age of 65, you may qualify if:
* you are living in the most exceptional compassionate circumstances
* you are completely or mainly financially dependent on children or grandchildren living and settled in the UK
* you have no other close relatives in your own country to help you
* your children or grandchildren can support you without needing help from public funds, and
* your children or grandchildren have enough accommodation, which they alone own or live in, where you can live without needing any help from public funds.
If she does not qualify for above, she can apply as a Family visitor.
You as her relative will act her sponsors. If she is succesful she will be entitlesto stay here for a maximum of 6 months after that she will have to leave.
The form she needs is here
http://www.ukvisas.gov.uk/resources/en/ ... 3073/VAF1B
You can download and complete here and then send it to mother in law for her to sign it and take it to the nearest British High Commission or Fedex/VAC office, along with the documents that are stated on the form.
You as the sponsor will need to show that you can support her both financially as well as accomadate her and pay her all her cost during her stay. You will need to show for examples details of your finanace (bank statements) employment details & salary as well as accomadation letter.
Write a letter with the application pointing out why and who she is visting(family/grandkids etc) and WHY SHE WILL RETURN HOME after the visit as you have to convince the ECO she is coming for a vist only.
I wont worry about the fact that she has no job or saving as this would not normally apply for a widow or an elderly person
Hope this helps
