Thanks for your question.
If you are a student, only your spouse, civil partner or dependent children are entitled to a right of residence.
Other relatives (including extended family members such as brothers, sisters and cousins) do not have an automatic right to live in the UK. To be considered, the extended family member must be able to demonstrate that they are dependent on you.
Thus, you will have to show that your moher is wholly reliant upon you and that there is no other family member capable of caring for her in her home country.
The ultimate decision in relation to your paplication will rest with the UKBA.
I hope this answers your question. If so, kindly click accept.
If you wish to discuss, please feel free to ask further questions.
