看了老师昨天给“香侬”有关I-864的回答，有点糊涂。
关于下面这个，老师说不用选。可是如果这样，item 10就该填“1”，household size不就少了一个人（父亲或母亲）吗？
-If you sponsor your both parents, you need to file "1" in Item 21. f, leave Item 9 blank. Thus,, your total household size will not 少了一个人.
part 3 item 9 :
I am sponsoring the following family members immigrating at the same time or within six months of the principla immigrant named in Part 2 above. Do not include any relative listed on a seprate visa petition.
第二个问题是，我给父母申请绿卡，收到USCIS的I-797C（receipt notice)已经有一周多了，可是在“My Case Status"里还是查不到，需不需要联系USCIS?
-Check it some time later. USCIS need some time to put the information into onlie system.
谢谢！
