How do I negotiate a later start date after signing the offer due to work authorization?

Hi, I'm a master student on F1 visa and graduating this May 15. I got an offer from a big company (a bank) two weeks ago and the start date on it is May 21. However, I applied for OPT around late March and expect to get work authorization around late June. The problem was that I was afraid of losing this offer at that time so I didn't brought up this actively while talking to hr and already signed it (I did mention that my work authorization might not be approved on the start date but the hr didn't follow up about that). I think I should follow up with them ASAP for their convenience. Do you have any suggestions that can make them more comfortable and willing to delay the start date for, up to 3 or 4 weeks?
