@borislav12 if the job you are performing is NOT as a professional employee ( see the list of benefits that a professional employee gets ) and is generally considered as a trainee and in furtherance of your education, , you are generally exempt from FICA even if you are a resident for tax purposes or even a citizen of the USA. Thus under some circumstances , medical students as a "resident" may be exempt from FICA because it is a required training and is part of their education.
Does this make sense ?
