International students, scholars and employees will need to apply for a Social Security Number (SSN) if the are working in the US. The SSN is a nine-digit tax ID number issued by the Social Security Administration.
If you are an international student, scholar or employee, you can apply for a SSN only if you are inside the US in valid immigration status and you have been authorized to work in the US. The following are examples of who can apply for an SSN:
Dependents: F-2 dependent family members are not eligible to work and cannot apply for SSNs. Dependents in J-2 or H-4 status are eligible to work only if they have an Employment Authorization Document (EAD) card issued by USCIS. Dependents who do not have work authorization may be eligible to apply for an Individual Taxpayer Identification Number (ITIN).
|Category||When To Apply|
|Newly Arrived F-1 Students or J-1 Students, Scholars, and Student Interns||
|Continuing F-1 Students, J-1 Students and Scholars||
|F-1 Students on Post-Completion Optional Practical Training||
|Newly Arrived H-1B Employees||
*If you are a newly arrived F-1 student or J-1 student or scholar, you must first complete a confirmation of arrival with the International Center before you can apply for a SSN. This is because we must confirm your arrival in the US in the appropriate visa and activate your F-1 or J-1 SEVIS record. Once your SEVIS record is activated, we recommend that you wait at least five days before applying for an SSN, to allow Social Security's databases to be updated with your immigration information.
Once you have completed your arrival process, it is recommended that you apply for a SSN as soon as your eligibility has been established. You cannot apply for a SSN once you are within 15 days of completing your program and/or employment, or after you have left the US.
Step One: Prepare Your SSN Application Materials
To apply for a SSN, you must prepare several documents as listed below. Please review this information and follow instructions carefully.
|Visa and Employment Situation||Required Supporting Document|
|F-1 Students with On-Campus Employment||
|F-1 Students with Curricular Practical Training||
|F-1 Students with Employment Authorization Document (EAD) card for Optional Practical Training (OPT) or other type of F-1 employment||
|J-1 Students with On-Campus Employment or Academic Training||
|J-2 Dependents with Employment Authorization Document (EAD) card||
*Note: J-1 students and scholars sponsored by an external organization such as Fulbright should get authorization letters from their sponsor, not the International Center.
Step Two: Go to a Social Security Office with your documents to apply for a SSN
Update (April 13, 2022): Many SSA offices have resumed walk-in services as of April 8, 2022. SSA still encourages applicants to call ahead to the SSA office serving your area (see below) to confirm the correct procedures, but recent reports indicate that the offices in Cambridge and Boston are now seeing individuals on a walk-in basis. Please note that in most locations only a limited number of people may be allowed into the office at a single time, and masking and social distancing rules are still in effect.
Social Security generally requires that you contact a SSA office that serves your residential area. To find the Social Security Administration office for your neighborhood, use the SSA Office locator. The most commonly-visited Social Security Administration offices for Tufts students include those indicated below:
STEP THREE: Wait for your SSN
When you submit your SSN application to the SSA office, ask for a receipt confirming your application. Provide a copy of the receipt to your department hiring manager. The SSN card should follow in the mail within 3-4 weeks after your application was received at the SSA office.
When you apply for your SSN, ask for a receipt to show that you applied for your number. Social Security can take 3-4 weeks to process your application. Once they have processed your application, they will send you a Social Security card containing your SSN to your US mailing address.
For security, keep the card in a safe place upon receiving it - do not carry it with you on a daily basis and do not send your SSN through insecure means such as over emali.
Students: If you are working at Tufts, you must report your SSN to Tufts Support Services (TSS) or add your SSN to the Student Information System (SIS) yourself following these instructions. If you are also working in an on-campus job at Tufts, you will also need to submit your SSN directly to the I-9 verification system following the instructions on the Access Tufts SSN page or the I-9 Verification page.
Other Employees: Report your SSN information to your department or center where you are working. Your department manager will provide further instructions about updating your Social Security information with Tufts.
The Individual Taxpayer ID Number (ITIN) is similar in format to a SSN. However, it is a temporary tax ID number issued to persons who are NOT working but receiving US income through other sources ("non-compensatory" income). Examples of non-compensatory income include income from a scholarship or fellowship that covers expenses such as food and housing or other costs outside of required tuition and fees.
If you are receiving income through work (employment), do NOT apply for an ITIN - you must apply for a SSN instead.
Here are some of the major differences between a Social Security Number (SSN) and an Individual Taxpayer ID Number (ITIN).
|SSN versus ITIN Comparison||SSN||ITIN|
|Eligibility and Purpose||Students and scholars who have an on-campus job or US employment authorization must apply for SSNs prior to or soon after starting employment at Tufts.||Students and scholars who are not working but who have taxable US income (e.g., taxable scholarships or aid that do not require employment, prizes, stipends, etc.) may apply for ITINs|
|Duration of Validity||The SSN is a permanent, lifetime number.||The ITIN is a temporary number that can lose validity if not used; see the Internal Revenue Service's ITIN web site for more information. The ITIN loses validity if the student or scholar later qualifies for a SSN.|
|Issuing Government Agency||Social Security Administration (SSA)||Internal Revenue Service|
International Center ITIN Processing: The International Center can assist you with getting an ITIN if you are an F-1 or J-1 student with a US source scholarship, fellowship, grant, or allowance that does not require employment (work). Note: in general, you do not need to apply for a ITIN if your scholarship is applied directly to your required tuition and fees. However, if your scholarship is paid to you directly to help you cover your own personal expenses, then it is generally considered taxable income requiring a tax ID such as an ITIN.
If you need to apply for an ITIN, contact Heather Varnet via email at Heather.Varnet@tufts.edu to schedule an in-person appointment. You must bring the following with you:
