I'm also made redundant recently. I remember my employer told me that I should inform the home office about it before I was made redundant.
1. Can you please confirm that it is the sponsor's(my employer) responsibility to notify the home office about my redundancy?
2. When I first my tier 2 visa, there was a letter from HO as well saying that:
"If your employment ceases prematurely you must return your passport and BBRP to the HO within 28 days in order for them to update your records. If you do not submit your passport and BRP we will update our records with the information held on file."
Based on this, should I send my BRP and passport to HO?
Many thanks for your help.
