According to the Immigration Department, the adjustments for talent admission schemes, which include General Employment Policy, Admission Scheme for Mainland Talents and Professionals, Technology Talent Admission Scheme, Immigration Arrangements for Non-local Graduates, and Admission Scheme for the Second Generation of Chinese Hong Kong Permanent Residents, will be put in force from Monday (Feb 27).

Applicants of these schemes must declare whether they have any criminal convictions during their application.

The adjustments came after a once-jailed Chinese scientist, He Jiakui, was granted a visa to enter the city.

The labour and welfare chief Chris Sun Yuk-han later announced that all the Top Talent Pass Scheme applicants, including those who submitted applications but were yet approved, would undergo the declaration procedures.
