Protect Our Liberian Community Act of 2019 This bill establishes that a national of Liberia shall be deemed to have registered for temporary protected status as of April 1, 2019, for three years, if the national registered for such status at any time and was present in the United States on March 30, 2019, under deferred enforced departure. Temporary protected status is available to nationals of certain designated countries, and such aliens shall have work authorization not be removed from the United States while the status is in effect. Liberia's designation was terminated as of May 21, 2017. The President has granted deferred enforced departure status to Liberian nationals, which prevents their removal from the country and provides work authorization, until March 30, 2020. Individuals with temporary protected status under this bill shall have employment authorization for the three-year period, and any lapse of authorization between April 1, 2019, and the enactment date of this bill shall not affect the validity of such an individual's employment authorization document.
