Hi ,

My Wife has H4 Valid till May 2019 , but my H1B is expiring in April ,2018 and I applied for extension , I would like to know if my extension get denied then can she staty till 2019 or she has to leave the country with me . Also how much time USCIS give after deniel notice , as I am worried if my H1B extnesion decesion comes after April 2019 then how much days I will get to wind up everything  as I spent more then 7 years in this country.

Thanks!!

Once you lose H1 status, she loses H4 status. Nothing stops you from staying over for a few weeks to wind up.

As long as you stay inside US with pending decision (upto 240 days) after H1B extention filing it is legal.
