Processing time for B2 visitor visa EOS

[domino1975]

I am planning to apply for extension of stay for my parents. Can someone tell me how long does USCIS take to review the case. Where can I check the processing time. Are there any websites that publish the processing time.

If there is no RFE, then less than 60 days, you can check the timeline on their website under I-539.
