Thank you for your info. The reason my employer is withholding the FICA is because I have additional TPS but when I go through Sprintax they say that qualify for FICA return since there are SSN and Medicare withheld in my W2.
If you guys have any source which will help me to clarify that having TPS but not working with TPS-EAD will qualify me for FICA return then I will be more than thankful.
