A Social Security number is intended to accurately record your earnings in this country. Most employees are required to pay a certain percentage of their earnings to the Social Security System through the Federal Insurance Compensation Act or what is generally referred to as the FICA tax.
You must have a Social Security number in order to work. Therefore, if you plan to work you should apply for a social security number. You may be able to use your Social Security card as one of the necessary forms of identification required on the Employment Eligibility Verification Form (Form I-9). The Payroll Office uses this information to determine deductions.
