I want to know how requirement does it tke to get one year business visa

You need to provide those documents: your passport and copy of its data page, a completed application form attached with a passport-style photo, an introduction letter from your company, an invitation letter of a duly authorized unit in China, company certificate and tax clearance record, and recent 4-month bank statement.

Given wrong information here when you are not even in ghana..anyway chinese embassy in gh dont give one year visa anymore besides the maximum they give is six mnths if only you ve been in china six times...
