Sister In Law Visa Refused

Hi,

Has anyone been in a similar position?

My sister in law is from a poor village in Pakistan and she has No work experience nor qualifications, but married to a UK Citizen. She had a job offer to work in the UK. Her husband is disabled and receiving funds from the government due to his incapability of working. They also refused her on the grounds of her mother and father in law not being alive how will she support herself and husband or other way about.

We have 28 days to lodge an appeal.

Any advice would be appreciated.

Thanks.
