I am Indian travelling frequently to China for Business. Since i travel frequently single entry visa and double entry visa's were filling up my passport pages and also cost lot of money. At that time getting 6 months/1 yr multiple entry visa from India was stopped because of Beijing olympics. So i got one 6 months multiple entry visa issued in China. On expiry of it, i tried for a multiple entry visa in China, but couldn't get one because of Shanghai world expo. Then through an agent in HK i got one year multiple entry visa issued from Singapore. However personally i never been to Singapore. Is this kind of a visa considered legal & genuine.
