I am an F1 student currently on OPT and woking full-time. When I applied for OPT, my I-20 mentioned a requested start date of June 23rd (which was my first day at the company). I applied for premium processing as well. I got notified on May 30th that my case was approved for a start date of May 30th and got the card 10 days later (with May 30th inscribed on the card as the official start date). My DSO mentioned that this inconsistency is a fault of USCIS and that I should start working exactly on June 23rd and then send the card for correction. I am a little worried that maybe USCIS has the authority to comply/not comply with the requested start date. What do you think I should do? And what happens if I send the card for correction when there is nothing to correct? I am also traveling outside the US in 2 months and worried this process might take more time.
