Joan Thomas is part of the Windrush generation that came to Britain as the country sought to rebuild after the Second World War.
UK Prime Minister Theresa May met with Caribbean leaders and envoys, and told them "we are genuinely sorry for any anxiety that has been caused" over the harsh treatment of the Windrush generation.
The scandal over the mistreatment of Windrush immigrants from what had been British colonies has cast a shadow over the summit, which is supposed to strengthen Britain's ties to fellow Commonwealth countries as it prepares to leave the European Union.
Today some of the descendants of the Windrush Generation have been deemed "illegal immigrants" and have been asked to provide documentary evidence of their life in Britain, which they had not been previously required to keep and in some cases were threatened with deportation. The UK-EU agreement risks producing a new Windrush generation in the near future.
Most came with their parents in the 1950s and 1960s; some on board the HMT Empire Windrush, which docked at the port of Tilbury in June 1948 carrying 492 people from the West Indies.
What is happening to them?
Mr Bristol's lawyer, Jacqueline McKenzie, said: 'He would come into the office and say: 'Will I ever get my passport?' We saw him get more and more depressed and anxious.
It is unclear how many people belong to the Windrush Generation, since many of those who arrived as children travelled on parents' passports and never applied for travel documents - but they are thought to be in their thousands.
But those who failed to get their papers in order are now being treated as illegal, which limits their access to work and healthcare and puts them at risk of deportation if they can not provide evidence of their life in Britain. In 2017, he lost his job at a school where he had worked for more than 15 years.
His daughter Samantha Barnes-Garner said the problem started in 2013, when she booked flights for her father to return to the United Kingdom and he was told at check-in that his indefinite leave to remain was invalid. "To take someone out and just throw them out, like they had no worth", Braithwaite said.
Irrespective of whatever statutory or treaty provisions are ultimately put in place following Brexit, the Irish in Britain have reason to be concerned that bureaucratic policy and political posturing will make Britain an increasingly hostile environment, even for long-term immigrants, and even for the Irish.
In recent months, the British media has been reporting about a growing number of similar cases.
In November past year, he was detained again and booked on a plane to Jamaica two days later.
Certainly, it does not sit right therefore for these British citizens to be denied access to health care and services at this stage of their lives when they perhaps need them most and knowing full well that many of them would have laboured as teachers, nurses etc.to ensure that the integrity of the said British system was maintained.
What has the reaction been?
After a long and expensive battle with the authorities, Bryan received his right to remain in Britain in February - but nothing will change the trauma he and his family have been through.
But Labour has disputed this, saying the Home Office had earlier said the decision was taken in 2010.
Here, she tells Sky News she has called a Home Office helpline with her concerns over warnings that she and her peers could be deported unless they can prove they are entitled to be in the UK. She said she was "not aware of any person being removed" and vowed to find out from High Commissioners of the Commonwealth countries. One of her vocal critics on the issue is the leader of the Scottish Conservative Party, Ruth Davidson.
During the meeting at Downing Street, May told Caribbean leaders, "I want to dispel any impression that my Government is in some sense clamping down on Commonwealth citizens, particularly those from the Caribbean".
