亲爱的8老师，不好意思再麻烦您。
根据程序我在网上填写DS-261表格。我选择我老公作为Agent。
但是当我上网填写是，第一页填写的是Principal Applicant’s Information
然后是 姓， 名，和Email地址，
再然后是Have you already legally immigrated to the U.S.
and no longer need to apply for an immigrant visa?
-Say "No".
我糊涂的是，这些 information 到底是填写谁的呢？
-It is the beneficiary's.
这里的 Principal Applicant是谁呢？
-It is the beneficiary (your son?) who will apply for the immigrant visa in the US Consulate outside US. This form is filed by the beneficiary.
我试着打电话给NVC，但是老说线路busy，call them later。只好再一次请教您。谢谢
