Welome to ITAMP!

We are looking forward to your visit to ITAMP. Please read this page carefully

The information here contains details that will impact your expense reimbursements. We've included this information to inform you of ITAMP's travel policies and to help make your stay and your reimbursement go flawlessly. Once you have made your travel and lodging accommodations, let me know your itinerary so I can be sure everything is ready for your arrival.

Before Making your Travel Arrangements:   If ITAMP has agreed to reimburse your travel cost PLEASE BE AWARE that as a federally funded Institute, we can only purchase tickets on United States Flag Carriers. Travelers who purchase International airfares (defined as trips taking more than six hours of fly-time, including Alaska & Hawaii, but excluding trips to Canada and Mexico taking under six hours) follow the United States Federal Travel Regulations, even through less costly foreign flag carriers may be available. Please make sure that your ticket is written on an American Airline ticket stock and lists the American flight numbers. When booking your flight please note that due to the open sky's agreement, ITAMP is able to reimburse flights from European Union carriers when flying out of the home country of the airline. For example if traveling from the UK you can fly on a UK carrier. This should save everyone some money and allow your reimbursement to stretch just a bit further. A helpful website regarding government travel regulations is Federal Travel Regulation.

Accommodations: You must stay within the per diem guidelines for your accommodations. To find the current per diem for Cambridge visit website. Typically the range is between 150-180 depending on the time of year. Please also note that you will be reimbursed up to the amount agreed on in your invitation letter.

Depending on your circumstance you will submit a travel expense report, including receipts for all claimed expenses over $75. It is better to get some of this done before you leave. Please make sure to make an appointment with ITAMP's Administrator in order to process this paparwork. Should you have any questions regarding the paperwork or the appointment, please contact ITAMP office at (617) 495-9524 or e-mail (
