AT least two more nations are believed to be considering whether to sell passports under ''investment migration schemes'' to Hongkong residents, while the Marshall Islands has announced it will do so. The Hongkong consulates of Benin, a tiny west African country, and Peru have indicated that their governments are considering proposals for ''investment'' schemes whereby passports are issued for a price. Asked whether Benin, whose neighbour Sierra Leone sells passports and citizenship for US$28,000 (HK$217,000), sold passports through its Hongkong consulate, vice-consul Narender Vachani said: ''Not at the moment. ''At present we are not issuing any passports. That might change because the country is keen no doubt to promote certain investments but I have to get written permission from them before I can make any comment.'' Peruvian honorary consul Humberto Wu said Peru was about to launch a new scheme to sell passports in Hongkong but he could not give details. Peru had previously sold passports through the firm Blooming Strong in Hongkong for about US$35,000 (HK$271,000) without a requirement for the ''investor'' to visit the country. ''It was an official scheme but it didn't work out too well so the Government of Peru decided to do away with it,'' Mr Wu said. ''I think [under the new proposal] there are going to be other requirements attached so you actually do have to spend some time in the country.'' The Peruvian consul-general, Gabriel Alejandro Pacheco Crespo, refused to comment. At least two consulates, representing Sierra Leone and the Pacific archipelago of Tonga, sell passports to Hongkong residents under so-called investment schemes. The Dominican Republic consulate denies selling passports to investors but diplomatic sources and at least one immigration consultant say that it does. The Marshall Islands, which recently approved the sale of passports, has decided to open a Hongkong consulate to ''advance business opportunities'', including the sale of passports and citizenship. The consulate is to open on October 1.
