I got my h1b in 2011 Oct and I was asked for RFE as well, and it was exactly same situation as you wrote above except mine was not for renewing. RFE does not mean they denied your visa.They just request addtional information to see why the employer has to hire you. Don’t worry too much.. Just go ahead and talk to your attorney, and I am sure they already know what to do. In my case, my attorney had to attach stack of paperwork (about 30pages) including my detail job tasks, and I had to pay extra $1000 for that.(!) My attorney said USCIS became extra picky especially recent H1b visa applicants… As long as your paper looks good, you will get it. FYI, it took me about extra one month. Good luck to you (and sorry for typing in Eng. )
