All applicants must have authorization to work for Pear Therapeutics in the U.S. In certain circumstances it may be advantageous to Pear Therapeutics to support the application(s) for temporary visa classification and/or sponsor applications for permanent residence so that a foreign national colleague can accept or remain in a work assignment in the U.

Pear Therapeutics may at its business discretion decide to or refrain from obtaining, maintaining and/or extending the temporary visa status and/or sponsoring a colleague for permanent residency and /or employment eligibility, considering factors such as availability of qualified U.S. workers and the colleague's long-term prospects for securing lawful permanent residence, among other reasons. Employment applicants requiring immigration sponsorship disclosure, when initial application for employment is made, whether or not they are legally authorized to in the U.S. and, if so, whether that authorization permits them to work in the job they seek.
