8老师: Questions regarding Application Form (DS-260). Thanks so mu

Hi 8老师,

I am hleping my sister families to immigrate to the US. I have received an email from NVC for the immigration application. Right now we are still working on Application Form (DS-260). There are questions in the application (DS-260) after pertitioner (which is me) asking information for Social Security and Background and Social Security Number etc. I am a little confused. Those questions after pertitioner should be answered from pertioner (me)or benefiaries (my sister's family' members)? When I read those questions, they sound like the questions are for me. Please explain. Your help is really appreciated.

Thanks.
