Hi Everyone,

I got my ILR few days ago.

I need some help regarding applying for my spouse dependent ILR.

1.What are the documents required can i just apply with all my documents showing my wife is dependent on me?

2. how long does it take as my mother in law is ill we need to go to Bangladesh soon.

3. Will there be any problem in getting her a visa or she can get is straight away without any probelm as i have already got mine.

Please help me out.
