It seem like the RFE is related to your employer side not you, sometimes they need to show current tax filing, earnings and revenues, sometimes those documents take some time to prepare. These documents will be same for other employees too they are sponsoring. Some employers are on bad standing on sponsoring, so they might check those things. Good thing RFE is not related to your Job or education. At this case I don't suggest PP since the result will be very soon, lets be positive and say it will get approved then that's very good, what if its not, and send you another RFE then you need to plan alternatives and sometimes may take time. One more thing can you extend your OPT or this is your final extension? If so plan of doing that as well. I would say plan for alternatives just in case so that whatever process, regular of PP you do, you have backup. Good Luck sathi
