Filing H1B with Inhouse project .?

Hi Again

Thanks for anwsering my other queries. Here is another problem I am worried about now.

Got extension approval till 2014 but I got my stamping rejection at New Delhi consulate, I was in EVC model and not able to submit client letter because client didn’t provide letters to consultants.

This year another staffing company ready to file cap exempt H1B with In house project and same project documentation they have used for some other employee and that got approved. so this is kind of my employer is my client and I have to report my employer only.

Please let me know Is it good to file H1B with staffing company having Inhouse project or Is there any chances of stamping rejection with this.
