My mom is here as tourist, due to virus we kept her in US and decided to file i130 ,her visa expires in May but didn't hear from USCIS.what to do?

  As you have already filed an I-1130 petition, you should also file the I-485 application for adjustment of status if you have not already done so. You should attach a copy of the receipt of I-130 filing to the I-485 application so that U.S.C.I.S. is aware that there is a pending I-130 petition. Upon the filing of the I-485, your mother would be in a state of grace with U.S.C.I.S. in which she would be allowed to stay during the pendency of the application.
