My H1B Visa Extn

My H1B Visa Extn is filed and received the Recept notice on June 26 after that no updates. Pls let me know the SLA for the extn to be approved after the receipt is received.

You can look at processing times for I-129 Extension of Stay on USCIS for your processing center. That would give an idea when to expect action on your petition. There is no SLA per se.
