H1B, H4 Visa

First of all thanks a lot to this forum and excellent people, it helped me a lot for my interview preparation.
I felt my experience would really helpful to people who wants to know negative results as even i was trying to find more refusal results in this forum.

Coming to my background, I have more than 8 yrs of experience with one of top MNC in India and my petition is through small US company.

Interview dates:
OFC: 19-Dec-13
Interview: 20-Dec-13.

My H1b Visa is under administrative processing and I got 221(g) green slip. I was asked to submit further documents as proof. Following was interview conversation.

Employer Name:
Client:
Salary in US
Highest Qualification
Then asked any client letter.
I told i will be working at my employer location and showed MSA between employer and client
Then he asked, there is nothing mentioned about you and your project and responsibilities, thus we need a client letter.
I tried to convince him that client will not provide client letter if employees are working from Petitioners place. I have a job description from employer and showed it to him.
After verification of Consulate letter, he replied that, there is no information about the project description and it states only job duties. He said he need specific project description document and he cannot approve Visa with out it.

I tried to convince him again with my job duties mentioned in Consulate letter and told him I will be performing these duties from Employer location.

 He asked me , so you don't go to client location at all.
I replied that I can attend business meetings at clients place but no need to work at client's place. As my work related to development enhancements, I can work from my employer location rather than client location.

Then he started asking how many employees are working from employer to Client. I replied.

 He asked me how many employees are working at Client site and how many employees are working at petitioner site.
I tried to reply and he finally concluded that please send me the details of how many employees are working at client site and at petitioner site and their salaries and gave 221(g).

Valuable suggestion from experience is, if you work for client, client letter is mandatory, otherwise project description document should be essential. Please be specific for these documents from your petitioners.

Please also help me in following queries

It would be really helpful, if any of you could send me the sample or template of a Project description document looks like, so that I can follow my employer to get the similar one.

Should I submit my passport at VAC along with the required documents to be submitted, as it is not mentioned in 221 g to submit the passports and we cannot predict the timelines of administrative process cases.
