我和老公无子女。我独立担保我父母同时申请境内调整身份。请问我父亲的864表和我母亲的864表中，Part 5第6项是不是应该空着，因为864表此项的instruction 说 “Enter the number of lawful permanent resident whom you are currently obligated to support based on your previous submission of Form I-864 as a petitioning sponsor”? 既然我父母谁都还没有取得绿卡，谁都不应该算入此处，是么？所以第8项Total Household Size应该为3（我+老公+父亲or母亲）？谢谢指教！
