Hi Riya, I graduated in May but applied for OPT in April which I kinda feel now is a bit late, March could have been better. Haven’t gotten a response from USCIS now tho. Heard it takes 3-5 months. For the NCLEX, once u get I clearance from my school after exit and graduation. I then apply for the license and NCLEX. Also, prior to OPT application I worked with my college international office and got a new I20 that’s needed for the OPT application and NCLEX registration.
