Working at CITP

The Center for Information Technology Policy welcomes new visitors annually. The practical information in this section of our website should answer most of your immediate questions and help you familiarize yourself with our center, the University and the surrounding area.

Please contact Center Manager Laura Cummings-Abdo (, 609-258-2266) if you have any additional questions or concerns. Other staff members referenced in this guide are Event/Office Coordinator Jean Butcher (, 609-258-9658), and Associate Director Tithi Chattopadhyay (, 609-258-6167).

Housing

You may choose to apply for university housing through Princeton’s housing department. Note that you cannot formally apply for housing until you have received a Princeton ID and password. The Office of Information Technology (OIT) assigns the ID and password 90 days before the start date of your appointment.

  • Please note that Princeton University housing eligibility is not assigned on a first come/first serve basis. Click here for more information on the timeline and how the process works and here for the eligibility ranking.
  • Princeton University maintains an off-campus database. This database is updated almost daily by area landlords. You can set search parameters, and it will also give you the landlord’s direct information. Please note that incoming affiliates who have yet to receive their netID may register just below the login fields.
  • It is common for Princeton faculty members to sublet their residences for the year when they go on sabbatical. These notices are usually sent to department managers in the spring. Please let Laura know what you are looking for in terms of housing if you would like any applicable sublet notices forwarded to you.
  • Further, sometimes there are sublets on a site called TigerTrade. TigerTrade is an online exchange where you can browse listings that include things like furniture, books, cars, cribs, bicycles, sporting goods, etc. A netID and password are required to post items you want to sell or rent.
  • The Princeton Theological Seminary has temporary inexpensive lodging at the Erdman Center.

Princeton University ID

Your PUID card gives you access to many University facilities and services, such as the libraries, gyms, computer centers, and various cafeterias on campus. You will also need your card to access Sherrerd Hall after hours and the CITP kitchen and mail room.

  • Sherrerd Hall doors are unlocked weekdays 7 a.m. until 8:30 p.m. Your PUID card will give you door access to Sherrerd Hall on weekdays 8:30 p.m. until midnight.
  • On weekends Sherrerd Hall doors are locked, but your PUID card will give you door access from 8 a.m. to 8:30 p.m.
  • If you need to get in the building after midnight weekdays or 8:30 p.m. on weekends, you will need to call Public Safety to let you in (609-258-1000).
  • Also, please note if you ever forget your key and no one is around to unlock your office, you can call Public Safety and they will let you in, as long as you provide your ID.

To get your PUID, you need to go to the TigerCard Office (TigerCard a/k/a  PUID) located on the A Floor of the New South Building.

  • The TigerCard office is open 8:30 a.m. to 4:30 p.m. on weekdays. Once you receive your card, Jean will give you Salto access, which will unlock the CITP kitchen and mailroom doors.
  • You will need to update your card at a hotspot. The closest hotspot is located in the lobby of the Computer Science building by the stairs (the red brick building across Shapiro Walk from CITP on Olden Street). Please make sure you hold your card up to the hotspot until the red light turns green. If it does not work the first time, please try it again.
  • If you have any problems with your building or room door access, please see Jean.

Two additional TigerCard services to highlight: 1) the TigerCard office provides passport photos for $5, and 2) you can put money (Paw Points) on your card to swipe for payment at on-campus eateries, the U-Store and the Labyrinth Book Store.

Please note: Any changes in your name, home address or social security number must be reported to the TigerCard office. If you lose your card, there is a replacement fee of $15.00.

Princeton University netID

Your netID is what is assigned to you by the Office of Information Technology (OIT). Your net ID is what is used for your email and other University programs where you need to login. You cannot pick your netID, but if you would like to change your email name, you can do so by creating an alias. Please be aware that any Princeton University program you access that requires your netID login will be the original netID and not the alias.

Computing

CITP generally does not offer computers or laptops to its yearly visitors, but does have some access to used equipment, including desktops, monitors, keyboards, etc. that you may use for the year. Please contact Laura if you are in need of computing equipment or accessories.

The University offers numerous computing resources via its campus network, such as access to library catalogs, Lexis-Nexis, and J-STOR. Wireless Internet at Princeton University is accessed through eduroam.

In order to sign into your account for the first time, you’ll need to create a password and setup a Duo enabled device using the temporary password that will be emailed to you during the summer. It can also be found in the envelope that will be sent to you from Princeton OIT, which unfortunately will probably come to our offices, not your home address. If you can, please set up your email before you arrive (and “Duo Authentication”) to ensure your temporary password does not timeout.

Please see Laura if you have any access problems or need additional information to set up your email, connect your laptop to the network or printer, or general troubleshooting. You can also contact the Office of Information Technology (OIT) or call the help desk at 609-258-HELP (4357).

If you ever have a question about the legitimacy of an email, do not click on any links in the email. Please go to The Phish Bowl to see the latest phishing attempts.

Parking Permit

You can apply for a parking permit at the same time you get your PUID. The Parking Office and TigerCard office are both on the A level of the New South Building and open from 8:30 a.m. to 4:30 p.m. weekdays. A free parking permit for a specific lot will be issued to you on the spot.

Employment Eligibility I-9

The Immigration Reform and Control Act of 1986 (IRCA) requires all new and rehired employees to establish eligibility for employment in the United States. Princeton University cannot pay you or allow you to work until this verification process has been completed. Please note that non-US citizens must have employment authorization covering their entire Princeton University appointment period in order to be able to work and be paid for the full appointment.

You must fill out an Employment Eligibility Verification form (I-9 Form) in person within three days of your appointment start date. New employees should bring their original documents that establish identity and authorization to work to the front desk of the Office of Human Resources at 2 New South Building.

For a complete list of documents needed, more information, and to fill out the form, please go to: Form I-9.

Salary and Benefits


U.S. Citizens and Permanent Residents
Visitor salaries are paid monthly on the last day of the month. For those with ten-month appointments beginning in September, the first payment will be September 30. Salary and benefit information will be provided to you in packet sent to CITP a week or two before your start date, including direct deposit information. You can also access most of the information you will need here.

Non-U.S. Citizens/Permanent Residents
Any non-U.S. citizen/permanent resident who is at our institution and receiving payments from Princeton is subject to tax withholding. If the individual is from a country that has a tax treaty exemption, then he/she must apply for the treaty and must have a U.S. issued Social Security Number (SSN) or Individual Taxpayer Identification Number ( ITIN).  IRS Publication 901 contains information regarding tax treaties. If you want information about withholding, you can reference IRS Publication 515.

U.S. tax law requires the University to withhold income tax on payments received in the United States. You will receive information from the office of Non-Resident Tax Compliance at Princeton University regarding the Glacier system and you will be required to enter your visa information in the Glacier system within 10 days of arriving on campus. The signed Glacier forms must be provided to Nonresident Tax Compliance and Reporting Team (NTCR) located at 701 Carnegie Center, Ste 442A at least one month prior to the date of payment so that the correct tax withholding can be made; failure to do so may result in the maximum rate of tax withholding. The maximum tax rate that may be withheld from your stipend payment is 30%.

If Glacier has determined that you are eligible to claim a tax treaty benefit at an exempted or reduced tax rate and you have not provided your signed Form W-8BEN or 8233, then you will not be able to claim a tax treaty benefit. If not already on file, the completed forms must be submitted to the Nonresident Tax Compliance and Reporting Team (NTCR) located at 701 Carnegie Center, Ste 442A.

More Foreign Nationals or International Information can be found here, or direct specific questions to our office of Non-Resident Tax Compliance at ntcr@princeton.edu

Health Insurance


Medical Plan Information for Visiting Fellows who are U.S. citizens
Visiting Fellows with an appointment of at least 50% time or more for five months or more are eligible for coverage under a University medical plan. You will have 31 days from your appointment start date to elect medical plan coverage for yourself and/or your eligible dependents. If you do not make an election you will be defaulted into the High Deductible Plan with employee only coverage (no prescription plan and a $5,000 deductible). Upon your arrival, the Human Resources Office will provide you with a package of benefits information. This package will contain detailed information regarding your medical plan options, monthly cost information, and instructions on how to enroll or waive the coverage. Please review this information carefully, and if you have any questions, you may contact the Benefits team within the Office of Human Resources at 609-258-3302 or via email benefits@princeton.edu.

Medical Plan Information for Visiting Fellows on a J1-Visa
Health insurance for J1 Scholars and their dependents is a requirement for participation in the Exchange Visitor Program. Therefore, Visiting Fellows on a J1-Visa are eligible to elect medical plan coverage, regardless of their duty time or length of appointment. The University provides three different options for medical plan coverage for J1-Visa holders. You will have 31 days from your appointment start date to elect coverage for yourself and/or your eligible dependents. If you do not make an election, you will be defaulted into the J1-Visa Plan with employee only coverage. Upon your arrival, the Human Resources Office will provide you with a package of benefits information. This package will contain detailed information regarding your medical plan options, monthly cost information, and instructions on how to enroll or waive the coverage. Please review this information carefully, and if you have any questions, you may contact the Benefits team with the Office of Human Resources at 609-258-3302 or via email benefits@princeton.edu.

Research Expense Accounts/Other Purchasing and Reimbursement Information

A research/travel expense account is not given to most CITP visitors.

If you are given a small expense account and/or have been approved to purchase items/travel on behalf of CITP, please make sure you read the following information thoroughly:

  • The center and the University’s administration (the Office of Finance and Treasury and the Office of the Dean of Faculty) reserve the right to deny any expense reimbursement requests they feel do not align with the University’s guidelines, policies, and procedures.
  • All reimbursements must be done through Concur, Princeton University’s travel and expense program. You must have a Princeton netID and password to login, and set up a profile. Please designate Laura Cummings-Abdo as your Expense Delegate and Expense Approver. Laura can help you set up your Concur account.
  • The University has a Marketplace and it encourages all faculty, staff and visitors to go to it first to purchase items before looking at outside vendors. You must login to access the Marketplace.

Please note:

  • Receipts are required for expenses of $50 or more. Photograph or scan these receipts and attach them to your expense report in Concur.
  • CITP does not generally reimburse fellows for meals between other University affiliates (faculty, staff, fellows, students, etc.) even if you are discussing business (unless it is an official center sponsored event).
  • All meal receipts need to be detailed receipts, and not summary credit card receipts. Please note that alcohol alone will not be reimbursed, but is allowable if it is included in a group business meal.
  • Software for home computers may not be purchased with research account funds. The University owns rights to most but not all software.
  • Any hardware items purchased using any type of Princeton funds (expense, research, travel funds, and including laptops, iPads, etc.) must be returned to CITP at the end of your appointment period, as all equipment purchased with University funds is the property of Princeton University.
  • You are required to submit a Concur report for any expenses you have incurred the previous month. All expenses must be substantiated via a Concur expense report within 45 days of being incurred, or the reimbursement may be subjected to personal tax.

Q: Can I choose my own office?
A: Fellows, postdocs and visiting professors are not allowed to choose their own offices. Please note the CITP has limited space, so many visitors/postdocs/students are in group offices.

Q: Can I receive my netID early?
A: The Office of Information Technology assigns your netID 90 in advance of your appointment start date. They will not assign the netID earlier than that.

Q: When can I move into my office and how long I can stay after my appointment?
A: We try to be as flexible as possible, but what this means is that we’re being flexible to outgoing fellows as well as the next group coming in. For this reason, the date when you can move in or out is treated on a case-by-case basis. It’s best to check with Laura if you plan to arrive earlier than September 1 or you’d like to stay in Princeton past your end date.

Q: Can I mail packages in advance of my coming to Princeton?
A: Yes. Please use the following address: Center for Information Technology Policy, Princeton University, 305 Sherrerd Hall, Princeton, NJ 08544. If you have any questions regarding your package, please contact Jean or Laura. Please note that Jean is off most summers between June and mid-August.

Q: If I was given a research account, can I hire and pay a undergraduate/graduate student during my time at Princeton. If so, how?
A: Yes, you can hire a student to be a research assistant. If you would like to do this, please contact Laura, and she will help you place an ad, determine the pay rate, and determine if a certain student is qualified to work at the University.

Q: Can I bring my pet to the office?
A: Since some staff, faculty and new yearly visitors have allergies, we ask that members of the CITP community not bring their pets to their offices regularly.

Q: Do I have to pay for parking?
A: No, not this upcoming 2019-20 year. The university assigns one parking space per person. Typically, the assigned lot is the North Garage or Lot 21. Charge for parking may be implemented in 2020-21.
