My I94 expired on 30th Sep 2017. My employer filed H1B extension before I94 expiry. Employer received RFE on 26th March 2018 for my extension. My employer responded RFE on 1st May 2018. On 10th May 2018 i can see denial status on USCIS website for my H1B extension, but my employer says it has not received the denial notice(as of 15th May 2018). my questions are 1. how many days i can stay in US to wrap the things? 2. is there any chance i can come back to US again?
