I filed H1b + H4 Extension in regular processing on March 17th and inquired USCIS about case status because it was out of normal processing time. Got a reply from USCIS stating "My case was pending with security checks and it will be on hold until it is cleared". What do I do now? I did some google search and it seems it takes an year but no one responded that it got approved. I'm about to upgrade to Premium Processing. But looks like that doesn't help too.. Any inputs ?
