As you are aware, there was an announcement in September 2019 that the government will be introducing a new 2-year graduate immigration route from Summer 2021, similar to the previous Tier 1 Post Study Work scheme which ended in April 2012.
We have not had any further updates about the finer details of this route since the initial announcement, but will inform students once we have a clear picture of what is happening.
In the meantime you can read the information provide by the UK Council for International Student Affairs (UKCISA) at:

Also see the Home Office website with information on the policy statement
Again, as soon as we hear more we will update you.
