@Engineer101 generally FICA contribution has nothing to do with immigration/tax status. For a more specific answer to your case please answer at least the following:
(a) Are you yourself a US person ( citizen/GreenCard/Resident for tax purposes )?
(b) If you are a work visa holder then which visa ? When did you enter the USA?
(c) About your spouse -- which visa? When did she enter the USA? Which country is she from ? Are you from the same country ( if you are not a citizen/GreenCard )?
(d) If the spouse is a student ( i.e. not on "dependent" visa) such F, Q, M , J etc. visa , then when did she enter the USA ? Was this her first entry within the last three years ?
(e) Is spouse on EAD and if so when did this start ?
I will circle back once I hear from you --yes ?
