MULTIPLE re-entry permits for China will be issued with a validity of five years from the date of issue under an agreement with the mainland authorities. The arrangement runs from Monday to June 30, 1997, applying to people wholly or partly of Chinese race who have either acquired right of abode or been granted unconditional stay in Hong Kong. It will also apply to people not of Chinese race who have been granted unconditional stay in Hong Kong but who cannot obtain national passports and do not hold travel documents of any countries. Permits issued between July 1, 1992, and yesterday will be extended to the full validity of five years from the date of issue without charge. Permit holders do not need to approach an immigration office for renewal endorsement, which will be made at the first opportunity upon arrival at control points. The permits issued or endorsed with extended validity as from Monday can continue to be used on and after July 1, 1997, until their expiry.
