The Chinese government announced November 11th 2014 that visas for US citizens will be issued for a 10 year validity for Tourist and Business travel good for multiple entries. Five year visas will be issued for Student travel for study in China. Visas for travel to China used to be valid either 6 months or 1-2 years in validity. This change came about after the APEC meeting in China on November 10th. The visa change for US citizens and Chinese citizens traveling into the US is supposed to foster more travel and commerce between the two superpowers.
Travel Documents Systems specializes in processing this new 10 year Chinese visa, we are finding the issuance to be routine at this time.
