Need advise. Just now i realised I needed USPCC since i stayed there for more than 6 mos but it was 12 years ago. And it would take 10-12 weeks for the request to process. Unfortunately, I only have 72 days left to submit and i don't think ill be able to make it in time. What should I do here? Can i ask for extension or submit the application with incomplete PCC but mention in LOE?
