Updating employment records after green card

[Segun Victor]

I am in graduate school and I will still be here for at least the next 3 years . I recently received my green card through marriage . I did work (F1 on campus employment) and I still do work as research assistant at my school . As at now, my school does not know that I am now a green card holder. Is it important I inform the school about my new status ? If they know about my new status won’t that affect my paycheck (fica and medicare taxes ) .



If I file taxes without paying Medicare and fica taxes would that decrease my refund ?

Yes, it is important to inform your school.
Yes, now they have to report other taxes and may affect (lower) your paycheck.
