Thank you very much for your quick reply. I am grateful to your replies. Finally I have one question.
I have not yet traveled to USA and my wife is planning attend stamping, even before I travel. There are lot of advantages of having F1 rather than H4, some of them are
1. Eligibility for OPT/CPT, assistantships
2. No need to get stamped again in case my wife travels to India for her brother marriage
Hence we are preferring F1 rather than H4. As I am not in USA at present, still is there a chance that VO asks about husband's visa status ?
In DS160, we need to answer only one question related to this -- "Is your spouse/siblings/parents are in USA?". The answer for this question will be "No" from her anyhow. If she admits that I am married, I am taking a break from job and my husband is working here at India, I think she will get through stamping process.
Just to add to above comments, my wife has started preparing for GRE/TOEFL and higher education even before my petition is filed as she is really interested to pursue her higher education. She has excellent academic and professional background and she applied for 5 universities, all of them are listed in top 90 universities for MS in CS. She is not just doing MS with the intention of accompanying me. Hence respecting her intentions of pursuing higher education, I am preferring F1 rather than H4. But in case if in turn becomes a negative because of my H1, I would rather prefer H4.
Please let me know your thoughts.
Sorry for troubling.
