The Net Migration Report was submitted to the government in January but published on Tuesday, a day after the UK announced plans to cut the number of immigrants to the country significantly. The report was compiled by the Migration Advisory Committee, which is sponsored by Britain’s Home Office.

The office has not provided a clear answer on whether Hong Kong’s BN(O) passport holders who have migrated or plan to move to the UK under the bespoke pathway will be affected, only saying that Britain remained committed to the “humanitarian route” of the BN(O) scheme.

The report said the BN(O) pathway, which was categorised as a humanitarian visa, represented a “small but non-trivial” share of total net migration to the UK, adding that any decision to restrict such schemes “would likely not be economically costly”.

“[It was] not introduced for economic reasons,” the report said.

“The trade-off here is between the government’s desire to reduce net migration and the foreign policy and ethical considerations that led to the introduction of the visas.”
