After entering China, foreigners should apply for a visa renewal at the Exit & Entry
Administration Office of Public Security Bureau (at county level and above), if you meet
one of these 4 circumstances: @ change the purpose of visiting and stay; @ issued a
new passport (former passport will expire soon, or visa pages have been used
up); @ add companions after entry; @ group tourists need to stay in China separately. If
you fail to renew your China Visa, your current visa will become invalid, requiring you to
exit, leave China, and return home. Bear in mind that illegal stay would be punished.
When applying for a renewal of your China Visa, all foreign applicants have to submit the
required documents, accept inquiry and follow the basic application processes. The
authority will decide whether to issue a new Chinese Visa within 7 days from the date of
acceptance.
