My daughter, (an American currently living/working in the UK on a work visa - who has a resident card), was planning to meet us in Florida to attend a small memorial gathering for her Grandmother, who passed in November but due to Covid, etc.. we delayed the memorial due to the difficulty in gathering family members traveling during the pandemic. She understands she will have to do the before/after testing.. #9 (d) states 'to attend a funeral'. We are unsure of what proof to provide her with for the declaration? We are simply having a gathering at a family member's home (not a funeral home). Who can we ask this question to? She is nervous to show up at airport only to get denied (or fined) using this reason for travel.
