問題是父母在中國，兒子目前在美以H1身份工作，現在需要回廣州美領館麵試。問題：
1. 一旦通過麵試，原來的H1身份會同時作廢嗎？
-When they approve your immigration visa, they will not approve your H-1 visa anymore and also revoke your valid H-1 visa if you have one in your passport. Thus, you can not enter US to get the H-1 status.
2.由於假期有限，隻能回國2周，再回美國是否必須和父母同行，因為文件都在一個信封內，而父母不能馬上來美國。
-If you use immigration visa to enter US, you must enter US together with your parent (primary applicant) at the same time or must enter US after your parent enters US. You can not enter US before your parent enters US. You need to tell the VO during the interview whether you enter US together with your parent or enter US separately after your parent enters US.
謝謝知道的朋友答複。
