I began to work from 10/2001 using F1 OPT which is valid until 09/2002. I may have filed some employment eligibility document in HR in the first day of work. My H-1 was approved in 05/2002. Does it mean my status has been automatically changed from F-1 to H-1? Should I fill a new document in HR. One administration secretary (not in HR) gave me my H1 approval notice. I am curious to know how HR knows I am working as a H-1 or OPT.
Thanks,
