Visitors to Lincoln Laboratory will be allowed access to the facility for business purposes only and must comply with Laboratory policies while at our facility, including current policies regarding the use of face masks and social distancing.

Visitors to the Laboratory must also comply with the Commonwealth of Massachusetts COVID-19 Travel Advisory, effective March 22, 2021. The advisory states that all visitors entering Massachusetts, including returning residents, are advised to quarantine for 10 days upon their arrival.  Travelers in the following categories are exempt from this quarantine advisory:

  • Travelers who have received a negative COVID-19 result on a test administered not more than 72 hours prior to their arrival in Massachusetts. Travelers may also test out of the quarantine advisory after arrival in Massachusetts, as long as they quarantine until receiving a negative test result.
  • Anyone who is entering Massachusetts for fewer than 24 hours.
  • Anyone who is returning to Massachusetts after being out of the State for fewer than 24 hours.
  • Workers who enter Massachusetts to perform critical infrastructure functions (as specified by the Federal Cybersecurity and Infrastructure Security Agency) during required commuting to or from work and while at work.

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 may visit Lincoln Laboratory without first producing a negative test result or completing a 10-day quarantine. Additional information may be found here:
