Tier 4 Dependant information required

[yasir ali]

Hi,
I was on tier 4 and I got my ILR through the 10 year route. I informed my university on the 3rd of January 2020 that I have got my ILR. The response I had from the university was as follows:

"This email is to let you know that we have reported your change in immigration category to the Home Office.

As you have switched to Indefinite Leave to Remain, you no longer require a Tier 4 sponsor, and so the University has withdrawn its Tier 4 sponsorship.

Please note that this does not affect your studies or your Indefinite Leave to Remain. The report to the Home Office is only meant to confirm that you are no longer a Tier 4 visa holder at our institution"

My question is that my wife was/ is my tier 4 dependant.

1. So, will this curtail her current visa? The expiry of my tier 4 visa was jan 2021.

2. How soon do I have to apply to switch her category?

Please advise. Thanks in advance
