They can do either one. W#e applied for two extensions of 6 months. Didn't know we could apply for a year. My wifes PR came through days after her PR approval.
May I ask what reason for extension did you give for your parent's first 6 months extension and second did you receive the 1-year extension by now? I may have to apply for my father extension in a few months.
