I’m a US citizen. I’m about to apply for green card for my parents who are currently here on B2 status.
My parents only have notarized marriage certificate (jie hun gong zheng), which shows their names and birthdays. My notarized birth certificate (chu sheng gong zheng) shows their names and our relationship. Are these documents sufficient? Do we still need to provide my parents’ notarized birth certificate (chu sheng gong zheng)? Thanks!
