Newly grad from California but an International student

Hi. I am a newly graduate with my RN-ADN in a community college here in California. I am expecting to take my boards early this july. My problem is that I am on a student visa (F1-visa) and I am having a hard time looking for hospitals/nursing facilities that will sponsor work permit due to the regression. I believe my visa will expire in a couple months and so I hope to find an employer who would help with work visa. Does anybody know any hospitals/facilities that still provides work permit for nurses? My family lives in the USA but I am the only one with a visa problem (my parents are not citizens yet). I do not mind moving but I would love to stay within the California state (to family members).

Also, if anybody has any advice on how I can go about changing my visa from a student visa to a work permit that will be very helpful because since I am in the country already, I would prefer to do all those visa/paperwork here instead of (paying for an airline ticket) going back to my country (where none of my family is living in anymore) and doing all that from there all alone. All suggestions are appreciated. Thank you.
