1. for the 2022, since you were on OPT but a resident for tax purposes, you are immune from FICA taxes ( because this is training). You were probably working ( OPT ) with EAD in place.
2. For 2023 onwards though because you are on work visa and if you meet the Substantial Presence Test for the taxable year you would be subject to Federal, State and FICA ( Social Security & Medicare ) taxes just like an American citizen / GreenCard person ( US person ).
Is there more I can do for you ?
