Social Security Tax
Although all employees are required to obtain a social security
number for identification purposes, not all employees are subject
to social security tax withholding. Social Security is the U.S.
retirement fund, and contributions to that fund must be made by
U.S. workers. F-1 and J-1 visa holders are generally exempt from
this withholding, since it is expected that those workers will not
retire in the U.S. However, if you are in the U.S. more than five
years in a temporary status, you may then become subject to this
withholding. It is extremely important for you to talk with JMU's
payroll office before your first paycheck is issued so this
withholding or exemption from withholding is completed properly.
It is very difficult to retrieve this money if it has been withheld
