Hello there,
I am sorry to hear about the difficulties you and your mother are facing.
I agree with kay alami. There is no scope in the immigration law to sponsor your dependant parent if you do not have ILR. Of course, ILE for your mother is out of question. Please refer to the immigration rule 319
However, there is no mention in the immigration law of parent (s) who is applying for LTR based on sponsors in possession of LTR. . This does not mean that your mother has no right to join you if she is entirely dependant on you with compelling circumstances Plus accommodation and means of your support in the UK
Because, there is no legislation in such a scenario, one can legally argue the point with
1- Dependants of sponsors with Work permit.
2- Dependants of sponsors with HSMP
3- Dependants of sponsors with permit free training.
In addition to this the right to private and family life a under Act 8 ECHR
Since 2000, ECOs are unlikely to wave the right to appeal from an applicant whose sponsor is in the UK as this simply violates the human rights.
Your appeal will be heard and will probably be decided outside the rules. It will in fact sustain good legal argument. I am sure you are not the only one in this situation. If you go through the books and tribunals you will find similar cases.
It will take approximately a year or two at the most for your appeal to be heard.
My advice is
1-Consult more than one lawyer.
2-Get a good solicitor/Barrister.
3-Do not rely on IAS
4-Be well prepared for the hearing ( attendance, presentation, documentation and reliability)
5-Get the sympathy of the court on the day of hearing.
6- Get evidence that you transfer money to your mother from the UK
7-Collect remittance
8-Get Proof of contact such as telephone bills and letters. How often?
9-Show your visits to your country to see your mother.
10-Show pictures
11-Demonstrate your mother health status
12-Demonstrate your responsibility
13-Demonstrate a proof of ailing relation between your mother and others in your country.
14-Explain the culture in your country.
15-Explain the psychological aspects.
16-Proof of appropriate accommodation in the UK.
17-Proof of your employment and salary.
I must admit it is difficult to win this appeal but it is not impossible. Just fight hard for your mother. She has given you life.
Good luck
