Starting on September 22, 2020, at 8:00 a.m., only authorized visitors who have a valid COVID Visitor Pass will be able to enter MIT Lincoln Laboratory facilities. Each COVID Visitor Pass is good until midnight and requires an initial acknowledgement of compliance with the requirements for accessing the Laboratory, and a daily health attestation. A new COVID Visitor Pass must be obtained each day a guest visits before entry will be allowed. To access the COVID Visitor Pass app, visit Please see the user guide for more information.

Visitors to the Laboratory must also comply with the Commonwealth of Massachusetts COVID-19 Travel Order, effective August 1, 2020. This order states that all visitors entering Massachusetts, including returning residents, who do not meet an exemption, are required to

  • Complete the Massachusetts Travel Form prior to arrival, unless you are visiting from a lower-risk state designated by the Department of Public Health. As of September 12, 2020, lower-risk states include Colorado, Connecticut, Maine, New Hampshire, New Jersey, New Mexico, New York, Oregon, Vermont, Washington, and Wyoming.
  • Quarantine for 14 days or produce a negative COVID-19 test result that has been administered up to 72-hours prior to your arrival in Massachusetts. If your COVID-19 test result has not been received prior to arrival, visitors, and residents must quarantine until they receive a negative test result.

Note that visitors providing support to the Laboratory or any other member of the Defense Industrial Base fall under the exemption for "Workers Providing Critical Infrastructure Services" and thus do not need to fill out the Massachusetts Travel Form and may visit Lincoln Laboratory without first producing a negative test result or completing a 14-day quarantine. Additional information may be found here:

Defense Industrial Base support is defined as

  • Workers who support the essential services required to meet national security commitments to the federal government and U.S. Military, including, but are not limited to, space and aerospace workers, nuclear matters workers, mechanical and software engineers (various disciplines), manufacturing and production workers, IT support, security staff, security personnel, intelligence support, aircraft and weapon system mechanics and maintainers, and sanitary workers who maintain the hygienic viability of necessary facilities.
  • Personnel working for companies, and their subcontractors, who perform under contract or sub-contract to the Department of Defense (DoD) and the Department of Energy (DoE) (on nuclear matters), as well as personnel at government owned/government operated and government-owned/contractor operated facilities, and who provide materials and services to DoE (on nuclear matters) and the DoD, including support for weapon systems, software systems and cybersecurity, defense and intelligence communications, surveillance, sale of U.S. defense articles and services for export to foreign allies and partners (as authorized by the U.S. government), and space systems and other activities in support of our military, intelligence, and space forces. 

All visitors must comply with the Laboratory’s social distancing policy (stay 6 feet away from others except for fleeting contact) and face covering policy (a face covering must be worn when walking outside, in common areas, and in rooms where there is more than one person present).

The Laboratory may screen arriving visitors for elevated temperature through the use of thermal screening systems that measure skin temperature. Those who are assessed as possibly having an elevated temperature may be asked to measure their temperature with a handheld thermometer. If the temperature measured by the thermometer exceeds a health-based threshold, visitors may be denied entry.

Please be aware that building access for visitors is now only available through the S-Building main entry.
