我现在持有学校的H1-b签证。绿卡申请140已经批了，在排队中。明年6年的H1-b到期，届时会再延期。
我老婆上个月底回去探亲，我留在这里工作，现在她在国内准备申请H4签证回来。但她在填DS160 表时遇到些麻烦，不知道怎么填，想请大家有经验的帮忙指导一下。
1. 问purpose of this trip to US？选temporary work (H), 这个选的对吗？
priciple applicant ？这里应该填谁的名字呢？是我的还是我老婆的？
-You are the principal applicant, not your spouse. Make sure your wife completes the DS 160 Correctly. Read the following cited from:
http://totallyexpat.com/global-immigration-news/united-states-faq-for-form-ds-160-nonimmigrant-visa-application/
5. My spouse is the principal visa applicant and I am applying for a visa as his/her dependent. Form DS-160 does not seem to have any selections for the kind of dependent visa I need. How should I fill out the form in this situation?
If you are the dependent of a principal visa holder or application – for example, you are the spouse of an H-1B visa holder and you are seeking an H-4 dependent visa – the DS-160 online system will ask you questions about the principal to determine the appropriate visa category for you.
Once you begin filling out Form DS-160, you will be asked whether you are the “principal applicant” for a nonimmigrant visa. If you are a dependent, you should answer “no” to this question. You will then be asked to enter the name of the principal visa holder, the purpose of his or her trip, and possibly other information, such as the receipt number of the principal’s USCIS nonimmigrant visa petition or, in the case of a principal F student or J exchange visitor, his or her identification number in the Student and Exchange Visitor Information System (SEVIS). Your visa category will be determined based on your answers to these questions.
难道是填我的H1-b receipt number?
-Right.
2. Have you made specific travel plans? 这个选yes还是no啊？
-Say "Yes" because she has planned to live with you as your dependent (H-4 holder).
这个应填啥？因为我现在的H1B到期日是7/30/2015，但绿卡没下来，我老婆是否该填8个月到我的H1B到期日？
-Right.
