What documents are needed for China visa as explained below?

I am a US Citizen with permanent residence in Costa Rica. My husband and I are going on a cruise from alaska and will make two stops in China. I understand I need two visas, one photo, copy of my passport and residence card -is there any thing else i need? My brother is also going with us, he is an american citizen but resides in costa rica, he use to have his residence card but it is not active. can he also apply here and wht other documentation do you need him to submit. Thank you for your time and patience. Respectfully, Natalei Wanamaker Javier
