US Immigration: What happens when Title 42 is lifted?

After more than three years, a controversial Trump-era immigration policy known as Title 42 is set to expire on 11 May.

Officials are bracing for an influx of migrants at the US-Mexico border when that happens.

On Tuesday, US President Joe Biden acknowledged that "it's going to be chaotic for a little while" when the policy is lifted.

The policy has long faced fierce criticism from immigration advocates and some Democrats who believed it prevented many asylum seekers from coming into the country.

Republicans have argued that the policy should remain in place to stop illegal border crossings, fuelling an increasingly intense and politicised immigration debate ahead of the 2024 election.
