What documents do I need to get S1 visa and do I need bank account my brother working in China

Manny, as far as I know, the S1 type is issued those who intend to go to PRC to visit the foreigners working or studying in PRC to whom they are spouses, parents, sons or daughters under the age of 18 or parents-in-law, so I’m afraid you cannot apply for the S1 type. But you can try to apply for the S2 type. The required documents include your passport and its copy, the filled-out application form affixed with a half-length color photo, an invitation letter from your brother and copies of his passport and residence permit, and your relationship certificate. The bank account may be required, too.
