Prime Minister Theresa May will seek to reassure Caribbean leaders later that the Windrush generation will not be deported over paperwork issues.
The government has apologised after it emerged that some people who arrived from the Commonwealth decades ago as children were now being incorrectly identified as illegal immigrants.
The home secretary has announced a new taskforce to help those affected.
May will talk to the leaders at a Commonwealth meeting in London later.
On Monday the prime minister reversed her decision not to meet leaders to discuss the Windrush issue, which was raised by MPs from across the House of Commons in an urgent question session.
Labour’s David Lammy said that it was a “day of national shame”.
